Public bug reported: Binary package hint: xorg
I tested KMS + UXA on a Dell Latitude E6400 with an Intel X4500MHD according to https://wiki.ubuntu.com/X/KernelModeSetting. If I am logged in and initiate suspend by pressing Fn+F1, the screen is locked and then the machine suspends successfully. On resume I can instantly see the unlock dialog. Sometimes it then hangs before I am able to enter my password (i.e. the cursor does not blink, mouse unavailable, keyboard input completely ignored, unable to vtswitch). The system is still up and running (responding to ssh etc). If I try to restart GDM remotely, the display output doesn't change a bit. Several processes of the X session go into zombie state (according to ps). If I try to start e.g. gedit remotely while X is still running (but frozen), strace reports this and then waits: [...] select(4, [3], [3], NULL, NULL) = 1 (out [3]) writev(3, [{"l\0\v\0\0\0\22\0\20\0\0\0", 12}, {"", 0}, {"MIT-MAGIC-COOKIE-1", 18}, {"\0\0", 2}, {"\360\235\373\302\23\344\334G\256\331\304\247\376N\235\345", 16}, {"", 0}], 6) = 48 read(3, 0xe12110, 8) = -1 EAGAIN (Resource temporarily unavailable) select(4, [3], NULL, NULL, NULL Without KMS and with EXA (default setup on Karmic) I was able to suspend/resume 11 times in a row without a problem, with KMS and UXA I could only successfully suspend/resume a couple of times, most of the time it didn't work and required a reboot before the machine was fully usable again.
