Trident Cyberblade XP2 on Toshiba satellite A25, cant set screen resolution higher than 800x600

[mpitch]

Binary package hint: console-setup

The graphics processor is a Trident Cyberblade XP2 on my Toshiba satellite A25 S3072. After installing Ubuntu I cant set screen resolution higher than 800x600

I am a new user to Linux. Recently I decided to get rid of winXP on my Toshiba Satellite A25 S3072 laptop and install Ubuntu 8.04 Hardy release. After installing, the screen resolution is at 800x600 whereas the native resolution allowed on this laptop is 1024x768. I tried a few things including editing the xorg.conf file but I do not know much about linux and could not get it to work.
I would really love to use Linux but with this problem it is very hard to use because my 15.2" laptop seems to be a 10" one for now with 30% of the screen being black.
Thank you for any help that any of you can provide in this regard. I tried searching on google but could not find anything that could help me with this.

If this is a wrong forum for this issue I apologize in advance.

Please attach /var/log/Xorg.0.log. For help about configuring xorg.conf I'd suggest the forums.

Try the xorg.conf at http://www.searchtempoblog.com/index.php/ubuntu-804-hardy-heron-on-a-toshiba-portege-2010-how-to-change-the-video-settings/

I have a Toshiba Portege 4000 with a Trident Cyberblade XP and this xorg.conf sorted the 1024x768 issue for me.

Thanks for all the comments and suggestions.
I found a solution on ubuntu forums that worked for me. Dont know if this will work for all of you but on my Toshiba satellite it worked. Just add the block given below to your \etc\X11\xorg.conf file and see if it works. Just paste it below the input device section. After adding this you will need to log out and log back in.

After trying loads of things for a day, the following (based on mpitch's code above) worked for my Toshiba Tecra M1 with Trident XP4m32 graphics (1024x768, 60Hz LCD screen). My problem was that i could not get the option to choose a screen resolution higher than 800x600 (a common problem, judging by the fora).

after re-installation of xserver-xorg so that computer booted into its default (small screen) state, i:
1) deleted the last few sections of mpitch's code
2) changed the clock MHz to 63.5 (rather than 65.0)
3) adjusted the Modeline dimensions (and changed -vsync -hsync to -Hsync +Vsync)
4) added the Option "PreferredMode" "1024x768@60"
I can't say which of these small changes were responsible, and i also re-installed all the xserver-xorg packages again halfway through the above process, 'cause it seemed to be failing, though all was well on shutdown and restart - it restarted in 800x600, but i then had the option to change to 1024x768 in Screen Resolution.

thanks mpitch and good luck to others..
