Comment 60 for bug 1292398

Wow, what a day. Hoping for relieve on this bug I apt-get install'ed xfce. It has the same problem with a crashing settings-deamon (it has its own). And I noticed that even xrandr just crashed on, what I think, where completely sane inputs with a floating point exception. And I did not really like the output of xrandr showing LVDS2, LVDS-1-0, VGA-1-1, VGA2 with at least three of them always in a connected state. My impression is that this is a source for confusion. The reason may be that my laptop has what I reckon is hybrid graphics, i.e. two graphics cards:

% lspci |grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV635/M86 [Mobility Radeon HD 3650]

Then I noticed that I had not installed fglrx. I apt-get install'ed it, rebooted, logged into gnome3 as well as xfce, fixed the display settings to my likings, rebooted, logged in and, wow, it is still there.

The remarkable part about xrandr output: It has now LVDS1, VGA1, LVDS-1-1, VGA-1-1, but no '2' and only the first two are listed as connected.

So in the end it seems this is rather a bug of whatever Xorg driver was superseeded by fglrx (I am not at all an expert of these drivers of X). I wonder if all others affected by this bug have hybrid graphics too.

Lets see if the settings survive one more reboot.
