Ubuntu

Unbuntu Installed, but user keeps loging itself out.

Asked by Mark Thompson

I am installing my second only box ever with Ubuntu.

This machine is Heinz variety machine. PIII 450mHz, 512mb RAM with on board sound and Video card. The Video card reports as a 3Dfx and has 60mb given to it in the BIOS. The machine all so has a 40GB hard disk. Up till yesterday this machine had XP Pro installed and was used as a home file server (having 3 other 100+Gb harddsik, which are now elsewhere).

Ubuntu installed straight away and I can login in. However, the screen after a few seconds flickers and you are logged out.

- I have replace the keyboard and mouse just in case.

- I have repeated the installation 3 times just to make sure I had not messed up in anyway.

- I have forced the screen to 800x600 56hz refresh in the few second I get logged in. This has not worked.

Does anyone have any ideas,

Mark.

I suspect the video card and/or driver.

At the console (which you can get to with CTRL+ALT+F1) login and type this command:-

sudo dpkg-reconfigure xserver-xorg

To reconfigure the video system. One of the first questions it will ask you is what kind of video driver do you want to use. Note which one it is currently using and try using vesa or vga instead.

Once you have answered all the questions you can run the following command to restart the graphical environment:-

sudo /etc/init.d/gdm restart

Login, test and report back.

Thanks for this Alan.

Just to clarify at point. At what point do you mean at "At the console". Is this when waiting to enter the username/password?

Also on another point could you please let me know what to do to close off "https://answers.launchpad.net/ubuntu/+ticket/4138"

All the best,

Mark.

Yes, enter your username and password at the text prompt then follow my previous instructions.

Ticket 4138 appears to be marked as solved, which is fine.

On issuing the ctrl+alt+F1, the screen becomes a series of vertical black and white strips.

On booting Ubuntu, I have found you can press escape at one point and get a boot menu. Selecting the recovery mode, I then get a terminal.

The the above instructions to choice and used a VESA card and also VGA accepting the defaults for the rest.

Unfortunately, I am still have the same problem.

I have installed, Win98, followed by XP and then Ubuntu again. The former work fine, so am assuming there is nothing wrong with the card. Could it be because the card is on the motherboard? Should I just disable this card in the BIOS and replace it?

I set the screen resolution and refresh rate in System/Preferences/Screen Resolution. There I set the screen resolution to 800x600 56hz, to try and overcome the problem.

I believe this is
 Bug #68291: GDM Restarts after Desktop loads while using tdfx driver.

I have not tried the fix from here, but given that all but 2 of the computer I am moving to Ubuntu have these cards, I really will now have to see if I can do this without being connected tot the Internet.

It is worrying that the common Voodoo card does not appear to be supported in Edgy. This mean that I can only convert 5 of the 16 computers I planned from Windows to Ubuntu. Only three of those with Voodoo cards seems to work with a vesa or vga adapter. None of those with Voodoo's on the motherboard want to work.

So does anyone know if there is a fix issued?

Thanks everyone, Alan and Pertti for your help. Each little bit has moved me forward one step towards finding a solution.

Below is my method for installing an updated driver on Edgy, for a newly installed machine that does not have an Internet connection yet (therefore unable to setup wireless connection because of Graphics problems and use solution as defined in bug report).

*** On another machine:-

1) Get new driver and burn onto disk.The driver can be obtained from:-
ftp.debian.org/debian/pool/main/x/xserver-xorg-video-tdfx/xserver-xorg-video-tdfx_1.3.0-1_i386.deb

This can then be burnt onto a CD or DVD to transfer to the machine with the graphic card difficulties.

*** On new installed machine with voodoo reboot problem

2) Start using "recovery mode". This is done by pressin the "Esc" key during start and selecting recovery mode from the menu
2) Put the CD or DVD into the machine and Mount the cd rom drive. I managed this using the following command as I had used a DVD as the transfer media "mount /dev/dvd /media/cdrom"
3) run "dpkg-deb --extract /media/cdrom/xserver-xorg-video-tdfx_1.3.0-1_i386.deb temp"
4) run "mv /usr/lib/xorg/modules/drivers/tdfx_drv.so /usr/lib/xorg/modules/drivers/tdfx_drv.so.bak"
5) run "cp temp/usr/lib/xorg/modules/drivers/tdfx_drv.so /usr/lib/xorg/modules/drivers/tdfx_drv.so"

Once installed the machine is now working well. Apparently, libglide3 for Voodoo3 or libglide2 for Voodoo2 now needs to be installed. These are in the "universe" repository. A description on this is included in the bug report Bug #68291: GDM Restarts after Desktop loads while using tdfx driver.
