Summary: screen looses color detail when switching to VT1 and
back
Product: xorg
Version: 7.1
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]

My discussion about this with Alex Deucher can be found at
http://thread.gmane.org/gmane.linux.hardware.thinkpad/31161
I have an X24 set up to use Xinerama (until now, I will change this to
MergedFB) with the internal display at 1024x768 and an external display at
1680x1050. When I go to VT 1 and then back to X the laptops internal display
seems to be dropping to 8-bit color or something like that. At any rate it
looses a lot of color detail. The external display remains fine.
Alex had the following to say about this.

I suspect one the CLUT is not being restore properly for crtc1 so the
palette is wrong. Can you file a bug at https://bugs.freedesktop.org?
