X11 startup log
KDE->Leave->Lock Screen also gives the black screen. It recovers if I kill krunner_lock. Created attachment 303267 [details]
xorg.conf, for completeness
Tried the F9 Live CD on the same machine. This time it worked correctly (1440x900) using the internal video driver (there is no xorg.conf by default). I could also use the Settings->Display widget without error. Going back to F9-Preview, I removed xorg.conf and restarted, but the error is still there. I notice that when the display goes black there is apparently a desktop still present. The cursor changes shape (arrow or I-beam) according to where it is on the screen. I just can't see anything except the cursor. I just discovered the real cause of my problem. I'm a longtime KDE user, so in my new F9 I just logged into my account as always, and of course it has all the setup for KDE 3.5. Removing a few lines from .kde/share/config/startupconfig (the ones to do with randr) basically fixed the aspect ratio problem. I still have the Settings->Display problem but that may also be related to KDE 3.5. I set up a fresh test account and it doesn't have this issue. Could you be more specific which lines of .kde/share/config/startupconfig you have removed? We can put it into Release Notes or something. However, reassigning to KDE component, because it looks like something to do with migration between KDE versions. Sorry. I only just noticed this request because the problem returned after updating to xorg-x11-server-Xorg-1.4.99.901-29.20080415.fc9.x86_64. The lines I commented out are all those beginning kcmrandrrc* Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Still having this problem or has it fixed itself? The display resolution bug is still present, but in KDE 4.0.98-2.fc9.x86_64 it has changed somewhat: 1) On logging in, the screen aspect ratio is wrong (looks like approx. 1024x768 instead of 1440x900), and windows are stretched horizontally to fill the space. 2) Opening Settings->Display instantly corrects the aspect ratio to 1440x900, which had been set in a previous session, without any further user interaction. Windows resize to their correct proportions. The panel also resizes and has to be manually stretched to fill the screen width. Some lines from .kde/share/config/startupconfig: # kcmrandrrc [Screen0] kcmrandrrc_screen0_height="1024" kcmrandrrc_screen0_reflectx="false" kcmrandrrc_screen0_reflecty="false" kcmrandrrc_screen0_refresh="75" kcmrandrrc_screen0_rotation="0" kcmrandrrc_screen0_width="1280" None of this was put there by me. Ping? Now using KDE 4.1.1 and the problem appears to have gone away, i.e. when I log in the aspect ratio is correct and requires no adjustment. The .kde/share/config/startupconfig file is still there but the kcmrandrrc values are now correct, to wit: kcmrandrrc_screen0_height="900" kcmrandrrc_screen0_reflectx="false" kcmrandrrc_screen0_reflecty="false" kcmrandrrc_screen0_refresh="75" kcmrandrrc_screen0_rotation="0" kcmrandrrc_screen0_width="1440" This corresponds to my monitor. |
