Anatoly Berbeka, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1085837 Title: [Asus K40AB] Resume from suspend to blank screen Status in “linux” package in Ubuntu: Incomplete Bug description: After suspend to RAM, while resume I receive black screen, and high-speed fans. Nothing works, system seems to be stacked, Ctrl+Alt+F2 doesn't work, no reaction for Caps/Scroll lock. Only "magic keys" works, or hard shutdown holding "Power" button. I use notebook Asus K40AB with 2 ATi videocards: integrated 3200 and discrete 4570. Bugs only appears when PowerXpress is on. Using 3200 videocard for work (it's running X) and 4570 for some 3d (using DRI_PRIME). Setting OFF or ON at /sys/kernel/debug/vgaswitcheroo/switch doesn't make any changes. Ubuntu 12.10 with xorg-edgers/ppa (for xserver-xorg 1.13). Tried to use pf-kernel 3.6.7 and 3.6.8, but still have the problem. I think the problem is in GPU init, because without PowerXpress everything is fine. WORKAROUND: Turn off PowerXpress and set dGPU.
