Hi
I am having trouble with a ubuntu 10.4 install, the problem is sometimes it detects the display, and changes to its native res (something like 2048x1560) however other times it doesn't and then default to 1024x768, this
1680x1050?
wouldn't be a problem if it just stuck with one all the time, but it seams to take liberties about when it chooses with res to go with, and as this is a pc for my parents, it is somewhat annoying, any ideas?
How are you cabled into the monitor from the PC? Any KVM switches in the way? DVI or VGA cables? DVI can be a "better" choice, as the monitor information is sent down the cables to the graphics board. (Hence why a KVM switch upsets the balance. VGA cables suffer even more, as the information can be sent through the cable, but it seems pot luck as to whether the monitor manufacturer and video card manufacturer decided to support that feature)
(PS, its a fairly boring intel on board graphics chipset)
How is the video RAM specified? Is it dynamically shared with Main memory. It can be beneficial to "fix" the amount of video ram used in the Xorg.conf (or equivalent) Failing all that, have you looked at /var/log/Xorg.0.log to see what error messages are coming out? Cheers, Warren.
