I am also affected by this (or at least a very similar) bug on a Sony VAIO VPCEA laptop on kernel 3.0.0-14-generic (oneiric).
After the display blanks (e.g. if `xset s blank` is set), the laptop display is corrupted (pink and white vertical stripes) after resuming. An externally connected monitor turns back on correctly. I can manually trigger by running `sleep 1 && xset dpms force off` Running `xset dpms force off` (without the sleep) causes the display to cycle off and back on quickly, upon which it recovers correctly. lspci lists the video card as: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) lshw says: *-cpu description: CPU product: Intel(R) Core(TM) i5 CPU M 450 @ 2.40GHz vendor: Intel Corp. physical id: 4 bus info: cpu@0 version: Intel(R) Core(TM) i5 CPU M 450 @ 2.40GHz serial: N/A slot: N/A size: 1199MHz capacity: 1199MHz width: 64 bits clock: 133MHz capabilities: fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp x86-64 constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm ida arat tpr_shadow vnmi flexpriority ept vpid cpufreq *-display description: VGA compatible controller product: Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 02 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:42 memory:f0000000-f03fffff memory:e0000000-efffffff ioport:e080(size=8) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/814325 Title: fuzzy and corrupted display after DPMS cycles To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/814325/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
