https://bugs.freedesktop.org/show_bug.cgi?id=32556 Summary: screen flickers all the time with desktop image appearing only briefly Product: DRI Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: critical Priority: medium Component: DRM/Radeon AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: 3ntr0p13(a)gmail.com Created an attachment (id=41344) --> (https://bugs.freedesktop.org/attachment.cgi?id=41344) dmesg Machine is the same as in bug report 28331 although with different software components: Acer Aspire L5100 with an AMD Athlon 64 X2 Dual Core Processor 4000+, this time running a 64 bits debian squeeze. The machine is a small factor desktop machine designed around laptop components, so the graphic card is an integrated radeon x1200. When running a linux vanilla kernel 2.6.37-rc6, the screen flickers all the time making the machine unusable, while with debian kernel 2.6.32-5 such "flick to black" event occur from time to time, making it annoying but usable. While booting with radeon.modeset=0 the problem doesn't exhibits itself The following packages version from debian squeeze are installed: xserver-xorg 1:7.5+8 xserver-xorg-core 2:1.7.7-10 xserver-xorg-video-radeon 1:6.13.1-2+squeeze1 Please find attached Xorg.0.log, dmesg, register dumps for ums and kms for that machine (when booted on 2.6.37-rc6).

This problem is known under debian squeeze with kernels 2.6.32-18, 2.6.32-13, 2.6.32-20, 2.6.32-25, 2.6.35-1~experimental.1, 2.6.36~rc6-1~experimental.1, 2.6.39-2, 2.6.39-2-686-pae (basically all tested kernel since KMS appeared) More information can be found on the debian bug tracker: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=583120 Here are some test: single user mode with KMS ========================= 1) boot in single user mode (see [1] for result of `ps aux`) 2) remove unused modules (see [2] for reslut of `lsmod`) 3) `echo freezer > /sys/power/pm_test` ; `echo disk > /sys/power/state` the freeze successes (stuff happens then bash comes back) 4) `echo devices > /sys/power/pm_test` ; `echo disk > /sys/power/state` the screen remains black, power and battery LEDs on, kernel doesn't answer to sysrq single user mode without KMS ============================ 1) boot in single user mode with `radeon.modeset=0` on kernel command line (see [3] for result of `ps aux`) 2) remove unused modules (see [4] for reslut of `lsmod`) 3) `echo freezer > /sys/power/pm_test` ; `echo disk > /sys/power/state` the freeze successes 4) `echo devices > /sys/power/pm_test` ; `echo disk > /sys/power/state` seems to succeed (stuff happens then bash comes back) single user mode with KMS, noapic, nolapic ========================================== Same test with `noapic nolapic` on kernel command line; Same result as "single user mode with KMS" single user mode with KMS, acpi=off =================================== Same test with `acpi=off` on kernel command line; The system doesn't boot, so I can't test Hope it helps, feel free to ask for more tests, Notes ===== [1].

[Bug 38465] New: Display flickers when setting power_profile
by bugzilla-daemon＠freedesktop.org 19 Nov '19

19 Nov '19

https://bugs.freedesktop.org/show_bug.cgi?id=38465 Summary: Display flickers when setting power_profile Product: DRI Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel(a)lists.freedesktop.org ReportedBy: egore(a)gmx.de When calling something like echo "low" > /sys/class/drm/card0/device/power_profile my display flickers a single time. This is okay-ish, but on Microsoft Windows the clock changes do not cause such a flicker. There has to be some kind of trick to achieve that and it would be great if this would work an Linux, too. Tested on vanilla kernel 2.6.39 with libdrm 2.4.26 and xf86-video-ati 6.14.2. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
