Maverick ati xorg freeze booting with external monitor

[jerrylamos]

Binary package hint: xserver-xorg-video-ati

With external 1280x1024 screen set on and laptop screen off in System Preferences Monitors, boot hangs showing splash screen with kernel 2.6.35-5-generic. Boots fine with kernel 2.6.34-5-generic.

Updated today, then booted O.K. to the external monitor with the laptop screen blank as desired.
I presume this bug is fixed.

Thanks,
Jerry

[jerrylamos (jerrylamos)]

Not fixed. Updated to 2.6.35-6 and X hangs during boot again.

Attached see Xorg.0.log, xsession-errors, dmesg obtained with ssh from another pc on the network.

Jerry

[jerrylamos (jerrylamos)]

Oops, no .xsession-errors. The one in the dump is from a couple days ago.

Sorry, Jerry

[jerrylamos (jerrylamos)]

radeon.modeset=0
fixes it, I think, booted a couple times O.K.

Tried it by hand on boot editing the linux line, then by altering /etc/default/grub to
quiet splash radeon.modeset=0
worked both times.

Do note on another of my pc's booting Maverick with intel driver I use
i915.modeset=0

Maverick KMS is buggy on two of my three pc's. The one that is booting O.K. has Radeon Xpress 200. I'll check it tonight to see if KMS is in fact on.

Jerry

[jerrylamos (jerrylamos)]

2.6.34-5 will boot with KMS on.
Ctrl-Alt-F1 switches to text screen O.K.
Ctrl-Alt-F7 to switch back to desktop fails. Screens freeze. ssh still works.
Attached is dmesg & Xorg.0.log by ssh from another pc on the net.

I've forwarded this bug upstream to http://bugs.freedesktop.org/show_bug.cgi?id=28937 and subscribed you to it. Please follow up with them in case they need further information or wish you to test something.

[Bryce Harrington (bryce)]

Btw, given that the issue shows up as a regression between two kernel versions, that pretty much points to this being a kernel bug rather than xorg. Refiling.

(Btw, when you run into problems like these, that seem to be narrowed to the kernel, please do go ahead and file directly to the kernel, I guess there's not really a need to go through xorg with these each time.)

Today's ppa still has the same problem:

Linux version 2.6.35-999-generic (root@zinc) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #201007281008 SMP Wed Jul 28 11:18:42 UTC 2010

radeon.modeset=0 and I'm able to boot O.K.

Without the external monitor it will boot with KMS on.

Jerry

[jerrylamos (jerrylamos)]

The bug does still occur with today's ppa, 2.6.35-999 Wed July 28. I did re-verify Alpha 1 2.6.34-5-generic still boots O.K. in KMS mode with the same xorg and all the other maverick updates up to July 27 so it would appear to be a kernel bug.

Alpha 2, kernels since, and today's ppa requires radeon.modeset=0 in the linux boot line to boot successfully.

Jerry

[Martin Vysny (vyzivus)]

I can confirm that as well. Note that in 1 out of perhaps 15 cases the X starts successfully, but there is garbage on screen instead of the ubuntu boot-up logo.

[jerrylamos (jerrylamos)]

Problem still here with Maverick Alpha 3, which is daily build 20100803:

Linux version 2.6.35-14-generic (buildd@rothera) (gcc version 4.4.5 20100728 (prerelease) (Ubuntu/Linaro 4.4.4-8ubuntu1) ) #19-Ubuntu SMP Mon Aug 2 01:43:35 UTC 2010

dpkg -s xserver-xorg-video-ati | grep Version
Version: 1:6.13.1-1ubuntu1

Martin Vysny, I see the garbage too. It occurs about the time KMS would have started?

Alpha 3 CD doesn't boot either, unless linux line modified wth radeon.modeset=0

Same problem with this card:
01:00.0 VGA compatible controller: ATI Technologies Inc M24 1P [Radeon Mobility X600]
This is on a Dell Latitude D810 notebook.
The radeon.modeset=0 workaround also works here.

[clickwir (clickwir)]

Upgraded to Kubuntu 10.10 Beta from Kubuntu 10.04, on reboot I see the UBUNTU 10.10 and the dots . . . . for about half a second, them I'm put to a semi-half-purple screen and it just stops there. I use the Magic Keys REISUB and reboot ok. I have an ATI HD Radeon 4830.

Doing the above mentioned radeon.modeset=0 works. I'm posting from my Kubuntu session now.

So, I guess I'm just another "Me too!" and if there's anything I can help provide to help get this fixed, I'm just and end user but I can try a few things and report back or give more info.

@jerrylamos , regarding the Ctrl+Alt+F keys, try adding "xforcevesa" to the linux line on booting. I have an older ATI and need that line or I get a white screen when I try any of the VT's

[sam tygier (samtygier)]

i think Bug #601376 is the same issue

[gpothier (gpothier)]

With today's updates I can boot into Maverick without radeon.modeset=0, so I guess this is fixed for me.

[jerrylamos (jerrylamos)]

gpothier,

I'm the originator of this bug, and I agree, it's fixed.

So whoever knows how to mark the bug as solved, please do so.

Thanks much for the fix.

Jerry

[clickwir (clickwir)]

Maybe I'm having a different problem, but I still need to use the 'radeon.modeset=0' in GRUB to boot.

Hi,

same problem here. I just installed a fresh ubuntu from 10.10 beta iso and when i tried to reboot it didn`t came up again. After removing "quiet splash" option from grub i saw as last message:

Checking for battery state

after adding 'radeon.modeset=0' to my grub config the laptop booted up normally

Additional Info:

[jerrylamos (jerrylamos)]

Working O.K. now with Beta and RC. Problem solved for me.

Thanks, Jerry

[Martin Vysny (vyzivus)]

I also can confirm that it works for me. Thank you!

[clickwir (clickwir)]

Still have to use radeon.modeset=0

Hell, even my wife is used to using it now. :-(

[clickwir (clickwir)]

I have fixed my issue by running jokey-kde and letting it find my video card and installing the FGLRX driver and use that instead of the RADEON driver.

I can now reboot to a fully graphical UI without having to do anything.
