Display problem in Ubuntu 6.06

Recommended Posts

Hi, after installing Ubuntu 6.06 I have a problem with my monitor. The image is displayed with horyzontal lines and the colors look funny, with strange stains.

FC4 & Ubuntu 5.04 worked ok, so i gues it is xorg 7.0 problem.

 

Please help me!!!

Try with:

 

press <ctrl>+<alt>+<F1>

 

sudo /etc/init.d/gdm stop
sudo dpkg-reconfigure xserver-xorg
sudo /etc/init.d/gdm start

 

You might backup your xorg.conf file first.

If that fails, post the xorg.conf or dapper and the one of a working distro (e.g. Fedora). When we compare the files, we might perhaps find something trivial. But it is more probable from what you describe that it is a problem with the Xorg scripts themselves.

Try adding this from Mandriva

 # Monitor preferred modeline (60.0 Hz vsync, 64.0 kHz hsync, ratio 5/4)
ModeLine "1280x1024" 135.60 1280 1320 1456 1696 1024 1028 1032 1066 +hsync +vsync

# TV fullscreen mode or DVD fullscreen output.
# 768x576 @ 79 Hz, 50 kHz hsync
ModeLine "768x576" 50.00 768 832 846 1000 576 590 595 630

# 768x576 @ 100 Hz, 61.6 kHz hsync
ModeLine "768x576" 63.07 768 800 960 1024 576 578 590 616

to you Ubuntu xorg.conf. Maybe it solves the problem. Apart from that I don't see anything in xorg.conf that could cause your problem.

I'm using an old Mighty Banshee video card. Ubuntu uses 'vesa' driver, while mandriva uses 'tdfx'. I have a 'tdfx' driver on ubuntu, checked that in synaptic. How do I tell xorg to use that driver and not 'vesa'?

 

I've tried to write 'tdfx' instead 'vesa' but then system can not recognize my monitor.

 

... and i'll try what arctic said now...

Basically, if the tdfx driver is definitely included in Ubuntus Xorg on your installation (and both of your xorg.conf files have this entry currently!), then it sould simply work by replacing vesa with tdfx. If it doesn't work then, then I am pretty sure that it is a bug. Otherwise, check if you have to install an extra package. As Xorg became modular now, this could be an explanation why it doesn't work.

When i posted ubuntu's xorg.conf i was in a middle of experimenting, so i added 'tdfx' later, sorry for a little disinformation.

When i run it with tdfx i get an error, which sais that modul tdfx was found but there are no suitable modes. :wall:

Have any suggestions?

Can you give us the exact error message please? Does it report "no suitable modes" found or "no suitable BIOS modes" found? This is important.
