for fun, tested using gdm, doesn't seem to be an issue there. Another possible ConsoleKit/display-manager interaction? Tested changes since 1.7.0-1, seems this is the culprit: * Thu Oct 08 2009 Adam Jackson <ajax> 1.7.0-2 - xserver-1.7.0-randr-gamma-restore.patch: Restore CRTC gamma on EnterVT. rebuilding 1.7.1-6 without xserver-1.7.0-randr-gamma-restore.patch makes things behave again. any ideas how/why this could be problematic? Scratch build for testing sans xserver-1.7.0-randr-gamma-restore.patch http://koji.fedoraproject.org/koji/taskinfo?taskID=1790732 Which 945 is this, exactly? Are you using KMS or not? I get this on an r7500 just switching vts from kdm. I cannot reproduce it from gdm. ajax: with kms on the r7500 $ lspci | grep 945 00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) 0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) with kms. it's a dell latitude d620 If it helps any, notting suggested in #fedora-devel, that when/if this happens to try ssh'ing in , and issuing: DISPLAY=:0 XAUTHORITY=/var/run/kdm/<whatever> xgamma -gamma 1 and that restored the display, and it remains functional from then on... I can do further vt switches without problems, at least until the next X server restart. I see exactly the same behaviour on an EeePC 901 with same chipset as above: 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) The xgamma command above works and fixes the same behaviour following a suspend-resume cycle. An xorg-x11-server build which should fix this is currently in progress: http://koji.fedoraproject.org/koji/buildinfo?buildID=140035 please test it and report whether it resolves this issue. Testing ASAP would be really appreciated, we're on a tight deadline for F12. Thanks a lot! -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers xorg-x11-server-1.7.1-7.fc12 tests out A-OK here, looks like we have a winner. +1 build is tagged, so closing. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers |
