@penalvch I don't know if this is a bot, but... yes, this bug DOES affect me, and yes, it's the same bug. Notice that the reporter, and other affected, had/have AMD APUs, and are also using the "radeon" kernel module? It's the same bug in the "radeon" open source driver, and it's still present. AMD A6-4455M APU with Radeon(tm) HD 7500G Graphics AMD A4-4355M (integrated Radeon HD 7400G). Mine is a A6-3400M, with a Radeon HD 6520G APU, and I also have this problem. The freedesktop bug #23103 linked here affects different generation of ATI/AMD systems.
And BTW, I'm sure there are other reports in launchpad related to this one. If you only had bots that, instead of posting random comments in the reporta, did the researching and linking job for you... lp.net wouldn't be the mess it is. -- 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/1093644 Title: [Samsung NP535U3C-A03DE] Blank screen on resume from suspend Status in “linux” package in Ubuntu: Confirmed Bug description: when resuming from suspend, the screen remains blank, while the system ist still operational (logging in using ssh works). * restarting X doesn't help ("sudo restart lightdm" through ssh) * disabling KMS (nomodeset) doesn't help, still blank screen after pm-suspend * updating to xorg-edgers kernel 3.7.0-7 doesn't help * mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ (3.8.0.999) didn't work either * playing around with acpi_os_name had no effect I tried following the debugging instructions from https://wiki.ubuntu.com/DebuggingKernelSuspend, but I have no /sys/power/pm_trace (even on mainline kernel) The system is a brand new Samsung 535U3C-A03 with an AMD A4-4355M (integrated Radeon HD 7400G).
