Screen resolution on Sony Vaio with dead Radeon chip
Hello Linux folk
I have a Sony Vaio VGN-S28GP where the Radeon chip packed it in last year. I have installed Ubuntu 9.04 and it works fine in the default vesa failsafe setup, but is stuck at 800x600, although the display area can be 1280x768. In XP I can get 1024x800. Does anyone have any suggestions about how to bump up the display resolution? Here's a few diagnostics: Code:
lspci | grep -i vga Code:
$ sudo xrandr --verbose Cheerio |
If you can, could you post the contents of your /etc/X11/xorg.conf file? It might just be a matter of adding the resolution you want to the list of modes there.

Thank you for the suggestion. I installed Jaunty (kernel 2.6.28-16) in failsafe mode and it seems to be only able to do 800x600. I've tried a range of changes to the xorg.conf file. Some that try to access the Radeon chip crashes the display. Most changes, that look legal, cause the xorg.conf to not be read correctly - it seems to hate any changes I make to the file. I was hoping for a way to reconfigure the failsafe mode.

Update on thread. I decided to upgrade the Sony Vaio with the dead Radeon chip to Karmic (9.10). The failsafe screen is now 1024x768, which matches what xp does. I have tried a series of xorg.conf settings using the "headless" setup in "Linux Format" LXF128, p.104-105. Of course the

So at this point, I don't have anything further that I can think of, unless someone knows how to change the default settings in the debconf database for the failsafe option, or can think of another approach. At least now under Karmic, the screen is a usable size, even though I lose the widescreen and a thin line at the top and bottom. So for once, an Ubuntu upgrade fixed something instead of borking a half dozen things that worked in the previous version. |
Follow-up on previous. I got into the bios and found a setting called
