Resolution not saved, proprietary ATI drivers, dual monitors

Postby leneve » Sat Mar 26, 2011 9:07 pm

Think the problem is caused by something getting reset on login. After reboot (but before login), the screen is set to the right resolutions for each monitor, but as soon as I login the display flashes and is set to 800x600 cloned single display.

Code: Select all

inxi -G (after setting the correct resolution)

Graphics:  Card ATI RS780M/RS780MN [Radeon HD 3200 Graphics] X.Org 1.7.7 Res: 1366x768@60.0hz, 1280x1024@85.0hz
           GLX Renderer ATI Radeon HD 3200 Graphics  GLX Version 3.3.10188 Compatibility Profile Context


Code: Select all

xrandr

Screen 0: minimum 320 x 200, current 2646 x 1024, maximum 2646 x 2646
LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
   1366x768       60.0*+
(resolutions snipped)
DFP1 disconnected (normal left inverted right x axis y axis)
CRT1 connected 1280x1024+1366+0 (normal left inverted right x axis y axis) 380mm x 305mm
   1280x1024      85.0*+   75.0     60.0
(snip)


Looked around in ~/.gconf and ~/.config but didn't see anything that screamed "display". Is there a default display config that is run on login but not updated by amdcccle? Maybe session state?

sudo aticonfig --initial
which you've already run, saves the configuration in "/etc/X11/xorg.conf".
Back to the situation. I would have run:
1. gksu amdcccle
to change resolutions. Then
2. sudo aticonfig --initial -f
to make a new and updated "xorg.conf" (don't need to backup the file. It is done automatically)
3. Reboot
