Hi,
since upgrading from F16 to F17, I have a weird problem with the
monitor settings on my desktop machine.
I'm using the nouveau driver. The controller is an Nvidia GeForce 7100
GS. The controller is somewhat older, it has one DVI and one VGA plug.
Attached are two LCD monitors running a single desktop spread over both
monitors.
Running under F16, everything worked as expected. With F17, every time
I boot the machine, the monitor attached to the VGA plug is wrongly
adjusted, but always in a different way. Sometimes it's just a bit off
and text on the screen is flickering. Sometimes the entire picture is
too wide, sometimes it's off to the right, or to the bottom, etc.
Either way, every morning I now have to press the magic key sequence
on the monitor to readjust the picture.
Did anybody encounter the same problem? Does anybody know how to fix
this, perhaps?
For the records, I found the reason for this problem. It was apparently
caused by a grub update. Grub2 was using the same maximum monitor
resolution as I'm using in the GUI, 1280x1024. For some reason the
adjustment for the monitor is a bit different each time in grub, and the
monitor can only handle one adjustment per resolution. I changed the
grub2 settings so that the grub2 menu is shown in another resolution,
(GRUB_GFXMODE=640x480), and the problem vanished.
