And now that you mention it, I can also see some message flicker up for a very short time.
But than I get the grub menu and can chose kernel/os.
So at least for me, the workaround is usable (even if not really solving the bug?!?).

I have this same problem on a clean Ubuntu Natty installation with encrypted LVM (similar to comment #6). A possible cause can be that the fonts and other information GRUB loads from places other than /boot are not accessible at the boot time because they are located in the encrypted partition.

Previous versions of Ubuntu worked fine on similar hardware. What changed from 10.10?

Have this same problem on an Asus laptop i3 2.53 GHz with lvm + crypt.

Interestingly, initially I *upgraded* from Maverick to Natty and the problem didn't occur. After a clean install of Natty it started occurring.

Guido Nickels (gsn) wrote :

I was finally able to workaround the problem here.

The script /etc/grub.d/00_header does some font path detection stuff and if that fails it doesn't set any gfxmode (neither the default "auto" nor anything defined manually in /etc/default/grub).

The font path is /usr/share/grub, but I have a separate /boot partition and the script doesn't seem to know how to handle this situation correctly, leaving me without fonts and gfxmode.

So, I just copied /usr/share/grub/*.pf2 to /boot/grub and ran update-grub again. Voila, I got my gfxmode and a working unicode font, too.

P Jones (deerfieldtech) wrote :

Just wanted to confirm that comment #24 worked for me on Natty final, after an alternate install in which I selected LVM with encryption for / . Seems to me that grub goes looking for the fonts at boot but the volume they are on is still encrypted at that time and therefore unaccessible. Moving the fonts to the grub directory solves the problem.

Martin Spacek (mspacek) wrote :

I too hit this problem with my old Thinkpad T41 with radeon 9000 (rv250) graphics. I installed natty from scratch from the alternate disc (on usb) with lvm + encryption. I have "nomodeset" in my /etc/default/grub to allow the system to suspend:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Copying the *.pf2 fonts over to /boot/grub and running update-grub got rid of the "no video mode activated" error, but caused even worse problems: after reboot, I'd get to a blank (purplish) screen, and nothing would happen. In retrospect, I may have been at the text mode encryption passphrase prompt, but that wasn't showing up. After Ctrl+Alt+Del, the system would reset, and this time the full screen graphical grub2 would come up, and I could proceed normally to the encryption passphrase prompt.

I then uncommented the following:


and commented the following:


and ran update-grub, and now I always get a small text mode grub on every boot. Not sure which of the above changes were necessary, but this might help someone (possibly me) in the future.

I was able to circumvent the error by pressing Ctrl-Alt-F1 and then Ctrl-Alt-F7, which brought me to a graphical screen with the LUKS password prompt.

Then, installation of Nvidia proprietary drivers seems to change the boot sequence so that it falls back to usable text mode on my ThinkPad T61p.

I can confirm that comment #27 also works on a Thinkpad W510 with Nvidia Quadro FX 880M and the nvidia blob. Thank you past Martin!

After messing around a bit more, it looks like all that was necessary to fix the problem I described in that post was commenting out the following:


No need to turn on text mode by uncommenting "GRUB_TERMINAL=console"

Just wanted to confirm that the method for number 24 works well for people with the encrypted partition (don't bother with the uncommenting stuff).

Just so anyone like myself out there doesn't have to look all over to figure out how to do simple commands (my first time ever using linux).

launch the terminal and go to the directory (cd)

    cd /usr/share/grub/

copy the font files to another directory (cp, needs sudo, and *.pft copies the three font files at once)

    sudo cp *.pf2 /boot/grub

then update grub

    sudo update-grub

This is not solely a problem with laptops. I see the same behavior on an lvm encrypted partition with separate raid1 /boot partition with a fresh install of natty. Natty was installed via i386 x64 alt disc in expert mode on a SuperMicro 7046T-H6R SuperServer with an ATI 5870 card.

I did *not* see this behavior when installing ubuntu 11.04 server amd64 using expert mode, with the same exact partition setup... (on different hardware though).

When copying the fonts to /boot/grub I get the same blank purple screen. The luks decrypt passphrase prompt is not displayed. I can switch terminals via the ctrl-alt hotkeys but the screen still does not update. I can only tell that switching is working by watching the numlock indicator. Trying to enter the passphrase blindly without first switching off and back to tty7 does not work.

Additionally, removing the fonts, running update-grub && install-grub /dev/sda restores the original broken behavior, including a working passphrase prompt.

I tried both xserver-xorg-video-radeon and fglrx and of course that has no effect besides breaking the nice video mode set via KMS when running fglrx.

I also just reinstalled natty via amd64 alt disc in expert mode on the same hardware. The same issue persists there for the same two kernels.

(Although, now I have a new problem: my cheap LCD monitor can't recognize the resolution requested by the GRUB screen. Ugh!)

So, this is verified as a font path issue. I have to say, this bug is a real stinker. It demonstrates that a new Ubuntu was released and nobody bothered to even try full-disk encryption before releasing it...?

Does anybody else miss LILO? I've had more GRUB problems in the past 4 years than in the previous 10 years with LILO! HEY GRUB TEAM, STOP BREAKING GRUB.

Sorry, had to vent. An entire product release was delayed due to this stinker.

Comment #24 seems like a viable workaround for some, but not for me.

After copying the fonts as per Comment #24, GRUB is now displaying at an insane resolution of something like 2000x2000 px at the boot screen and also when I get to a textmode shell. My cheap LCD won't show anything at all, and my fancy LCD can only display the top half of the screen.

I mention it here only because it seems related to GRUB not setting the video mode correctly. First, due to missing fonts (as per Comment #24), and now, due to who-knows-why.

This is on an integrated NVidia G-Force chipset. Everything worked fine under 10.4.

#24 did it for me too.
Fresh install of Ubuntu 12.10 (Daily), x64, Dell Lat. E4300 (Intel-Graphics), with unencrypted /boot, luks on /, swap and /home from Alternate-install.

But honestly - I do agree to #63.

Dude. You are clearly using the wrong distro. Ubuntu is the
dumbed-down-and-amped-up-with-eye-candy distro for the masses. If you
don't want eye-candy and you want defaults meant for "power users" you
really ought to look elsewhere.

Nico (nnico) wrote :

Same here after installing kubuntu to luks setup in LVM with a seperate /boot partition.

It shows the error message and then it takes ages untill ugly text comes up without any splash.

I remember having the same thing on my laptop, a little diffrent, it actaully showed the message a short time but then showed it right with splash if a remember right. Somehow now it completely got away without me doign any fix or drover install, maybe its there but that fast gone that i dont see it. I played arround with installig desktop enviroments KDE/GNOME/LXDE reinstalled and installed packages a lot maybe that changed something.

Seems everything referring to post 24 so i will try this now

This bug also affects me on 12.04. The solution in #24 did not work for me, no difference. Workstation with two ATI video cards. Seperate /boot, encrypted lvm (and and swap, but that probably doesn't make a difference.)

Asif (vadud3) wrote :

I did a fresh lvm+encrypt install of ubuntu 12.04 using alternate amd64+mac iso and I saw same error.

I followed the suggestion from comment #24 and just copied the *.pf2 files from /usr/share/grub/ to /boot/grub
and updated the grub. Now I do not see that error message anymore.

Thanks a lot!

I did as suggested in #28 and the disk decryption/password screen/box appeared. I was able to mount disks and log in. I installed the proprietary drivers, and on next boot I went right to the password screen, but there was no password box, just a text input line, and the font was large with the text overwriting itself. I then did as in #24, copying the fonts to /boot/grub, but on next boot my LCD kept saying "Out of Range" and I couldn't find any way to log in. (^Alt-Fn didn't work, ^Alt-Del forced reboot.)

Just a suggestion...

In general, I'd guess that most people are unable to do such things. I
don't know about anyone else, but I stick to stable releases for my systems.

In general, getting things like this tested would probably go a lot
better if you did backports to releases that most people are probably using.

Maybe there are enough people this bug is affecting that you might hit
one or two "previewing" 12.10. I dunno. I just know that I don't have
any 12.10 systems here.

outa (outa) wrote :

I commented on this in #51

I have two machines running 12.04 now (both with encrypted LVMs), one of which was updated from 11.10, where I experienced this error, the other was a fresh install. I don't get the error message anymore now, on either machine.

I still get this blank screen (greyish now :P), but I am not sure if that is normal or related to this issue. Because on one comp I applied the workaround in #44, on the other I didn't, but both behave the same now.

I have been running 12.10 on encrypted LVM in a VirtualBox virtual machine for a little while now and haven't seen this problem. I didn't have to copy any *.pf2 files to /boot/grub -- the file /boot/grub/fonts/unicode.pf2 was already present.

Colin Watson (cjwatson) wrote :

Brian, it works the other way round. I need to know that it's actually been fixed in the (lower-risk) development release before backporting to the (higher-risk) development release. I don't mind if a relatively small number of people are able to respond initially.

Got the same problem, but not after installing Ubuntu or the ATI-driver. After a kernel update to, I think, I had the error message once, then a week nothing and since then I have this error message all the time, directly before the old 'Sparse file not allowed'-btrfs-related error. Now, both of them are terminal style, white on black, then the splash screen with big and ugly 'ubuntu-mono' like 'Ubuntu' letters (BTW the same on shutdown with overlaid shutdown messages.).
One error message on startup was more than enough, don't need two!

I'm running 12.10 and I do not have a graphical prompt to enter the LUKS password at boot. I have to press one of the arrow keys to get a text prompt. If I install the flgrx drivers for my ATI card on my laptop I will then get a graphical prompt for my LUKS password, however I can not run flgrx drivers with Unity.

So this issue is not fixed in 12.10.

A year later and I'm still facing this issue, now on 12.04.2.

This time I installed LUKS on top of RAID on a Tyan-S3970. A Ctl-Alt-F1, Ctl-Alt-F7 got me to a text box, but updating, followed by installing the proprietary nvidia drivers, turned that into a text mode input. I used #24 and I now have a text box again, but it looks all blurry and doesn't fit the screen.

Anyway, it took a dozen tries to get this far, so I'm leaving it!

I'm going to try it again on that Tyan-S2865 and see if I can get it to work this time.

This flaw (or bug) has caused 2 different problems. It has prevented the desktop (/home/mark/Desktop) from being stable. At boot time (cold or warm) the objects on the /Desktop load, but after a few seconds vanish. The file manager behaves much the same way. When called or invoked the "Folder" icon on my left panel opens for a few seconds, then closes without being commanded to do so. At no time during the on-time for the computer can the file manager (Nautilus?) operate properly. Also, trying to fix this and being mislead by those with Unity or Compiz problem, I have reset my left panel and lost a number of application.

A few days later, I saw, at boot time, one icon which had the look or image of the "i'm still loading" the exact moment went by so swiftly I don't know for certain what it is. But, I decided to delete it. It had a filename extension of .jp2. Ubuntu's various apps cannot read a .jp2. After deleting this file and re-booting, I have the formerly lost desktop objects returned to their places on the /Desktop. For example. *.txt, .jpg, .pdf, user created directories "Trusty Tahr", desktop configuration file (application/x-desktop), .mp3 and such. And the file manager is working.

Some of the processes I did are here:

I had the same problem on my t430 with 14.04 LTS

I wanted text-boot and tried to activate it with "GRUB_TERMINAL=console". Since then i got the "no videomode set" error.

The problem coubd be solved with "GRUB_CMDLINE_LINUX_DEFAULT=noplymouth"(for text-mode) and "#GRUB_TERMINAL=console"("GRUB_TERMINAL=console" caused the problem on my machine)

Hope this helps

Post #62 from drs305 fixed the fleeting message for me too, 12.04, grub 1.99, GRUB_TERMINAL[_OUTPUT]=console, with force menu to show, i.e. no submenu, with help of GRUB_TIMEOUT=2, and commenting these 4 lines near the end of /etc/grub.d/10_linux:

# if [ "$list" ] && ! $in_submenu; then
# echo "submenu \"Previous Linux versions\" {"
# in_submenu=:
# fi

PS: if ever related, the native lcd is 1680x1050, and as so not listed in grub's vbeinfo only showing 1280x1024x4|8|16|32 and 1600*1200x8|16 around the native.

Confirm that this still exits in 16.04.
My machine is a Thinkpad T530 with NVidia NVS 5400M GPU. I've tried all the workarounds above, not fixing the bug. I doubt it's related to NVidia drivers.

This seems to be a theme problem. Running these commands fixed it for me:

sudo chmod a-x /etc/grub.d/05_debian_theme
sudo update-grub
sudo reboot

Also present in the 18.04. [comment #101 has solved the issue|]
How did you find, that it is a theme problem?
