Xorg log
I tried it with F14 alpha, and the same thing happens kernel-2.6.35.2-9.fc14.x86_64 xorg-x11-server-Xorg-1.8.99.906-2.fc14.x86_64 xorg-x11-drv-intel-2.12.0-4.fc14.x86_64 libdrm-2.4.21-3.fc14.x86_64 I tried kernel-2.6.36-0.12.rc3.git0.fc15.x86_64 on top of F14 Alpha, and the behaviour has changed. first of all, a regression, hotplugging the VGA display no longer caused the display to be automatically enabled. I had to run xrandr and then it switched to extended desktop. pressing Fn-F7 the 1st time gave me mirror mode with both displays in 1024x768. pressing Fn-F7 the 2nd time gave vertical lines on the LVDS and diagonal lines on the top part of the display with lots of flicker. The VGA display was black. pressing Fn-F7 the 3rd time gave vertical lines on the VGA and horizontal lines on the top part of the display with lots of flicker. The LVDS display was black. pressing Fn-F7 the 4th time gave extended desktop without corruption. Created attachment 450667 [details]
Same problem on F13, Dell D630
I'm seeing the same problem with F13 on a Dell D630 laptop. I use the menus to select mirror mode and dmesg explodes with the attacted messages. Screens are blank and the laptop keyboard is locked up.
network is still working, which is how I got these messages.
dmesg starts with:
[drm:intel_lvds_mode_fixup] *ERROR* Can't enable LVDS and another encoder on the same pipe
[drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on crtc f6921800
Waits a while then the rest starting with:
BUG: soft lockup - CPU#1 stuck for 61s! [Xorg:1696]
Same as bug #628906 ? With F14 it now works, both for VGA and DVI. And since I upgraded, I will not be doing any more testing with F13. OK, let's close this one, and if anybody here on CC list feels this is still an issue for her, please, open a new bug (and mention it here, so I can quickly jump on it). Thank you |
