Nian, I guess we're not seeing this issue, right? We did not see this bug with our building. I think it should be window manager's bug that window manager is not aware of the screen resolution changes well. For the X crash, you can debug X and give the backtrace info.

WuNian Greeting, this is scott from dell, we met this issue on system with intel graphic card GM965/GL960, and when i try to compare with the nvidia graphic card, i didn't find the rotation option from resolution dialog. so we can know this feature is supported from graphic card. and this issue occured during the rotation feature running,I think it is very related with graphic driver.my comment: 1.did you reproduce with GM965/GL960 hardware under ubuntu8.04? 2.if it's caused by window manager application, Is there any detail for analysis? Per my understanding from driver development, there should be the notify message after rotation ready, and other related application like window manager will change the may to response the click capture from the screen.if any misunderstanding, please correct me. when the issue occured, the mouse move on sreen is hard to be responsed. if it's the window mannager issue, the mouse move should be smooth,right? so I think it still need more infor to clarify the root cause. I saw your screen shot. After rotate, gnome generated new panel in the bottom of window, so we know gnome has detected the Randr event. But the origin bottom panel was not remove. This is window manager's responsibility. So the split window is caused by window manager. As for the X hangs up, you can check by not starting gnome: 1, enter runlevel 3 after start OS, you will on text console. (you can change the runlevel by using sysv-rc-conf) 2, run: X & 3, run xterm & 4, run metacity & (or compiz) 5, then rotate the screen to check if X hangs up. This issue can be reproduced only when compiz enabled. For metacity, rotation works fine. This issue can be reproduced only when compiz enabled. For metacity, rotation works fine. (In reply to comment #6) > This issue can be reproduced only when compiz enabled. > For metacity, rotation works fine. Is it still reproducible with current master branches of xserver and mesa Git? There were recently some fixes for rotation with compiz. I got the same problem with xserver 1.4.99.905, intel driver git head (the most recent update). I do not use compiz, only openbox + gnome panel. If I rotate the screen (in any direction), the xserver hangs and I got only black screen. If I run only Xserver (X :1.0), issuing xrandr --output LVDS --rotation left causes screen of garbage and unresponsive mouse cursor. I'm using ubuntu/intrepid, i965GM hw. (ThinkPad Lenovo T61) I can't see this on my T61 here. What about current status? Please try with current 2.5 release, and recent xserver release. ping Scott Zhang? Does this still happen? we might close this as lp has closed it... Thank you for your email, I 'm out of office on China New Year vacation and will be back in 4th Feb. I have limited email access, for EMPC ubuntu issues in following period: 23th - 24 th Jan; 1th-3th Feb. please contact David Wang(david_d_wang@dell.com). This shouldn't be issue now. Close as LP. reopen if you can still produce. Pi Boy (pi-boy-travis: 146) [bugsquad] wrote on 2009-04-27: Confirmed on Dell Inspiron 1520 with same graphics card, running 9.04. Only occurs if Compiz is turned on. Occurs with UXA and EXA acceleration. Adjusting severity: crashes & hangs should be marked critical. Thank you for your email, I 'm out of office today, any urgent please call me at 13661411928 I'm going to ignore the "split screen" thing, as it seems to clearly be a compositor issue. For GPU hangs, please attach the output of intel_gpu_dump with kernel 2.6.30-rc4 or newer. Does this still happen with UXA+DRI2? If not, please close as fixed. timeout, closing. Please reopen if you can provide intel_gpu_dump according to http://intellinuxgraphics.org/intel-gpu-dump.html. |
