Bug Description

I installed both the 32 bit and 64 bit versions of Ubuntu 10.04 Beta 2. After install, where automatically login, or request password was chosen the Ubuntu chimes sound and then the screen goes black. The chimes repeat every second or two, with the screen remaining blank. The system is completely non-responsive and the Num Lock, Caps Lock and Scroll lock lights flash on and off repeatedly on the keyboard. I am running Ubuntu on a Intel Core 2 Q6600, with 8Gb of RAM, A DFI Lanparty motherboard, Two ATI Radeon 4850's installed as crossfire. As is I cannot use 10.04 as both versions do this. I am reporting this bug from Windows. If there is more information needed please advise, I'm new to reporting bugs.

thank you for your bug report, you can boot the livecd image though or did you install in some other way? could you do an isntallation using normal password login, try to start your session, switch to a vt and copy the .xsession-errors something and add to the bug?

I can boot the livecd environment and run Ubuntu from there, but after the install when the full install tries to login is where the problem starts. I have tried both with a normal password login and having it automatically log me in. Password login was only tried using the 64 bit version, on that version both password and automatic gives me the repeating chimes black screen and blinking keyboard lights. 32 bit version was only the automatic, and I tried that after the 64 bit version failed.

I suffer the same problem with Ubuntu 10.04 (32 bit and already installed).

I get the login dialog, but when I press the login button, X is restarted and I get the login dialog again (up to the sixth of seventh time, that only the login dialog disappears and only the background is displayed [no X server restart]).

I don't know how it happened, but it might be due to an upgrade.

Which files are needed? I mean also directories.

Is there a workaround not to start X, login and then start X?

Thanks for your help,

Pablo

(BTW, the importance should be set to critical, since the system is unusable.)

Upgraded from 9.10 to 10.04 - login loop every single time - login screen showed up after a black screen blip. Shows a cl login prompt with the "correct" login ID name that disappeared right away.

Up pops a login screen. I login in, it takes the password, it starts to do something, the screen blanks and serves up the login screen instead of the deaskthop.

it didn't matter if it was a dual boot with windows XP AND Breezy, because I deleted them, reloaded 9.10 successfully and tried to upgrade again = login loop

it didn't matter if I loaded 10.4 with or without partitions because I deleted them. Another install, another login loop.

it didn't matter if I repartitioned the drive using Create Partition from the 9.10 ubuntu live cd and loaded 10.04 from a restart or a total shut down.

I am trying the shred command to see if maybe there was some kind of boot sector thing going on, the only thing I will know after that is my data is as gone as it can be and I truly regret hitting that little Upgrade Now button. It was a real vacation wrecker.

I agree that the importance of this bug should be elevated.

Fault verified as described above.

Proceedure was upgrade from 9.10 to 10.04 via internet upgrade.

Details:
Ubuntu 10.04 AMD 64-bit
Toshiba A210 laptop
Previous install 9.10, dual boot share with Vista.

Mitigations tested:
- login via recovery mode: fail
- login via previous linux headers: fail
- login via terminal script: fail (initial terminal login ok, activation of GDM *from* terminal results in this error - strange)

Fault seems rather severe. Access to machine is available via VT only. GDM environment is down.

Further suggestions for work-arounds welcome. I am now locked out of my main machine... Not a pleasant experience...

I agree and would suggest the importance of thie bug should be elevated.

PS: Perhaps an important note: I noticed that the menu for selecting a Gnome session was *gone* from the login menu with this fault...

install after shred command did nothing to change the login loop. main computer is down until this is fixed as far as 10.04 is concerned. Standing by for help - moving all duplicates to this one.

Can anyone attach a copy of .xsession-errors? I am no longer able to do so...

I do not have expertise to do this; working on getting my ubuntu "pal" to do
it. Will post by June 14, 2010 if can do. Internet connectivity reduced to
phone, pardon brevity.

I would like to know if this is something that is being worked on. I don't know how to fix this loop myself and it seems I do not understand where to start for a solution. If I knew where to look, I might could help. Right now - my computer is still downgraded to ubuntu 9.10. The upgrade still will NOT work. The clean re-load is all good fun until I reboot and the login loop rebegins again. arg.

Effecting me as well, but in my case the only update I can point to is a kernel upgrade. This could be a mis-match between X (or just GDM) and the recently upgraded kernel version number. The minor number went from 22 to 23 (that is the Ubuntu build number)... This has me locked out of my netbook! Because this bug can lock down an entire computer from use, it should be upgraded in severity!

10.10 came out, same bug. I implore you to open this bug for upgrade. "no activity" is result of complete disabling of MY computer for one, and I suspect upgrade information needed on HDD formatting. Please excuse the reference here (and not in Maverick Meerkat version bugs) but I think this needs to be tied into what will ultimately be MicroSoft around the boot sector. After bashing around I finally started locating directories and some terminal commands.
Observations: please note "the treatment"
   Live CD: 10.04 and 10.10 (same result)
      boots to a login screen
      login/password combinations return to login screen
      IE; does not work at all
      : no other behaviour

   Install Ubuntu 10.04 and 10.10 (same result)
      (before "the treatment")
      installs to restart and hangs on "Enter"
      hard power off to restart
      boots to a login screen
      login/password combinations return to login screen
      login/select safemode desktop/password starts as expected [in Safe Mode]
      seems to run as normal load for normal activity WHY SAFE MODE only?
      /dev/sda1, /dev/sda3, dev/sda4, dev/sda5, dev/sda6, dev/sda7, exist: but only 3 partitions were created during install AND AND AND AND the three partitions created "used the entire disk". How did I do that? I DON"T KNOW! and what happened to /dev/sda0 and ...2?
      : no other behaviour

      (after "the treatment")
      10.10 installs exactly as expected
      /dev/sda0 partitioned with 20Gb root sda1 & 470Gb home on sda5(???) & what was left as swap on sda7
      boots all the way to login screen
      login/password combination blinks, loads desktop, returns to login screen
      - info note? - in the 0.67 seconds it starts to show the partial desktop, it appears to be able to respond to GUI inputs before it dumps back to the login screen
      login/select safemode desktop/password starts as expected [in Safe Mode]
      seems to run as normal load for normal activity WHY SAFE MODE only?
      terminal command df - shows /dev/sda1 root, /dev/sda5 home (swap does not show I guess)
      Question - is it significant that /dev/sda1 and 5 seems to be written onto the disk as though there are partitions 2,3, and 4 still containing previous loads?

"the treatment"
failed load of 10.04 incensed owner to delete all information using Gparted from 9.10 Live CD
repartition did not change login loop - multi-boot grub was noted to contain WinXP, two previous versions of ubuntu AND 10.04.
shred command was used on 500Gb drive - lots of time wasted - no improvement. multi-boot grub still present
10.10 issued and loaded and login loop noted
owner deleted all information using 10.10 Install partition application and reloaded several times using incremental changes. exact same login loop. local support claims hardware issue. noted multi-boot grub still present.
used IDE to USB interface and used Apple backup computer's DiskUtiflity to format to journaling type?OOPS?
attempted to use 10.10 live CD
login screen loop
attempted to install 10.10 - upon reboot mutli-boot grub is gone
login loop again
boot to safe mode
not knowing anything about grub, tried to remove it usin...

no change in login loop after all that, and I accidentally wound up loading Natty Narwhal.

Let me rephrase my question -

My HDD was subjected to every data removal option short of scrap yard Electro Magnet or Low Level Format, and after repeated reloads from disc's and internet update and upgrades, does not allow me to login to the Ubuntu Desktop. Login is allowed with the Ubuntu safe mode option, this was noted at the same point where GNOME desktop option vanished [upgrade from fully updated 9.10].

Why does Ubuntu 11.04 (and 10.10 and 10.04) refuse all login/password combinations (just like a failed login) unless it is in safe mode?

If safe-mode only is the intended login mode I apologise for having missed that in the documentation, but it seems to me like there is something interesting going on here regarding how a totally erased backup persists via some bizarre USB/recycle bin/wiped HDD severed connection.

Thanks,
I have to change from 64MB to 32 MB and then Ubuntu 10.04 32 Bit booted normally :)

Is there another way around this bug?

I have an Acer Aspire 4330 laptop with the same login loop problem, but the BIOS doesn't allow me to set VGA share memory size.

I have gotten around the issue so far by installing slim in place of gdm, but I'd prefer to use gdm in the future if at all possible. Is there a way to change gdm to recognize the VGA memory limit since there's no BIOS setting for it?

Tony,

I apologize that my skills in this area are nigh nil. I will forward this
to a friend (nalioth) that is very helpful. you may find him in an ubuntu
help chat. when he responds - i will send it to you and that will be more
likely to help than my following postulations.

If you don't hear back soon enough - here is my two cents...
What I would do, having looked at page 29 in the attached tech data - they
point out in the book the setting is not configurable. is see if updating
the VGA bios, if not System BIOS would be a good idea. I noticed also a
multi-display setting/utility that probably never intended to stand behind
an open-source OS, so an update probably won't help this issue. If I get
down to updating BIOS - I just figure it is out of date and replace. As
illustrated below - very little is accomplished in the time (over a year)
taken to brute force investigate an annoyance if I can get around the issue
and on with using my computer.

my experience with this bug was that I was beat. After experimenting with
BIOS settings one setting at a time and hoping I did not have to try
changing two settings at a time (and back again), once I found the problem,
I tried "just one more" setting that totally blanked the screen (zero VGA
share memory size). I was so blindy furious I just built a new system. I
had learned so much from what didn't work. I forgot something simple like
removing the CMOS battery resets the BIOS. I opted instead for shoving it
into another case for a little child genius that loved the experience and
made a new system for 400USD in parts. Word to the wise - make sure that
if your new motherboard has a separate CPU power header, that your power
supply has that connector, or at least the adapter. Gosh darn those guys
at Fry's. Now running ubuntu 11.10 64 bit.

Then I remembered the CMOS battery remove and count to 10 (sage advice
there) install new battery. I set everything back and upgraded to 11.04
and then 11.10 and everything worked with the maximum VGA memory share.

Hopefully you can hold out til I get aholta nalioth.

The Terry
