I have ASUS K73SV notebook with dual graphics intel/nvidia. I'm using default intel driver, no proprietary drivers installed, and this bug also affects me.
1) Xubuntu installed from fresh daily build wakes up to login screen, after logging in screen turns blank, but hardware is alive - I can Ctrl- Alt-F1 to console and restart lightdm, after which I can login to desktop 2) Ubuntu installed from fresh daily build wakes up to login screen, after logging in all previously opened applications are closed, as if lightdm was restarted silently In both cases all previously run applications are closed, so suspend is unusable. In case of Ubuntu last information in /var/log/Xorg.0.log.old is: [ 6508.898] reporting 5 6 14 105 [ 6508.900] (II) intel(0): resizing framebuffer to 2624x900 [ 6508.901] have a master to look out for [ 6508.901] (II) intel(0): resizing framebuffer to 1024x768 [ 6508.903] need to create shared pixmap 1(EE) [ 6508.915] (EE) Backtrace: [ 6508.918] (EE) 0: /usr/bin/X (xorg_backtrace+0x48) [0x7fa053ba9a48] [ 6508.918] (EE) 1: /usr/bin/X (0x7fa053a01000+0x1ac739) [0x7fa053bad739] [ 6508.918] (EE) 2: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7fa052afe000+0x10330) [0x7fa052b0e330] [ 6508.919] (EE) 3: /usr/bin/X (DamageRegister+0x14) [0x7fa053b32c04] [ 6508.919] (EE) 4: /usr/bin/X (0x7fa053a01000+0xd53f9) [0x7fa053ad63f9] [ 6508.919] (EE) 5: /usr/bin/X (BlockHandler+0x77) [0x7fa053a5b267] [ 6508.919] (EE) 6: /usr/bin/X (WaitForSomething+0x134) [0x7fa053ba6f74] [ 6508.919] (EE) 7: /usr/bin/X (0x7fa053a01000+0x557f1) [0x7fa053a567f1] [ 6508.919] (EE) 8: /usr/bin/X (0x7fa053a01000+0x5990a) [0x7fa053a5a90a] [ 6508.919] (EE) 9: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xf5) [0x7fa05153dec5] [ 6508.919] (EE) 10: /usr/bin/X (0x7fa053a01000+0x44e7e) [0x7fa053a45e7e] [ 6508.919] (EE) [ 6508.919] (EE) Segmentation fault at address 0x10 [ 6508.919] (EE) Fatal server error: [ 6508.919] (EE) Caught signal 11 (Segmentation fault).
