Symptom: Whenever I switch to a vt terminal my display goes white. The display appears uninitialized as the color slowly fades, starting in the middle, until the whole screen is white. When I switch back to the X server everything is fine and the display comes back, until I do a vt switch again. The actual terminals are responsive so I can login blind and it works. Workaround: I found this by chance. If I use the radeontool command and do a sudo radeontool light off sudo radeontool light on the display comes back and everything looks fine. So now, before I need to switch to a terminal I run this in an X term, then switch: sleep 5 && sudo radeontool light off && sleep 5 && sudo radoentool light on Another workaround I found is that if I plug in an external monitor and direct X on to that, I can do a VT switch without this issue. The external monitor goes blank and the console appears on the laptop. This started with my gutsy upgrade to xorg 1.3.0. I have a "ATI Technologies Inc Radeon R250 [Mobility FireGL 9000]" running the opensource radeon driver. Module radeon: vendor="X.Org Foundation" compiled for 1.3.0, module version = 4.3.0 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02) I've attached my Xorg.0.log file, this includes the logging of two VT switches (last one starts at line 1247).

Update. I converted xorg to use the vesa driver and I do not see this problem. It only happens when specifying radeon (or ati).
I upgraded my to xserver-xorg-ati version 6.7.196 and now the card goes uninitialized after every mode switch. GDM->X, X changing resolutions, X to VT, etc. I placed the radeontool light off/on in my acpi lid.sh, so now I can get it back everytime by opening and closing the lid. But this problem seems to be getting worse in the latest revisions. Thanks, - Sean
Did an update to Ubuntu Hardy with X.Org X Server 1.4.0.90 and I am still seeing this issue. It seems that after an X session is started the display will never re-initialize back to a text display unless I do the radeontool toggle mentioned above.
Is this still an issue with a newer driver (6.9.0 or newer)?
closing due to lack of feedback.
