Bug#829403: tlp: screen flickers every 2-10 seconds
Hi, the T560 doesn't contain radeon graphics, so there's no point in trying RADEON* settings. The flickering occurs on battery power only? Then try to disable ALPM [1]: > SATA_LINKPWR_ON_BAT=max_performance Please provide the full output of (as root) > tlp-stat [1] http://linrunner.de/en/tlp/docs/tlp-configuration.html#alpm Regards -- Thomas Koch

It did not change anything. Hi, Thank you for your bug report. As suggested in [1], did you set the kernel boot option "radeon.dpm=1" when you tried changing DPM_STATE_ settings to "performance" ? [1] http://linrunner.de/en/tlp/docs/tlp-configuration.html#radeon Also, do you use the free Radeon driver or fglrx ? AFAIK, TLP works only with the free driver (and besides, fglrx had a history of problems regarding power management, and has been removed from sid anyway because it's not maintained upstream anymore). If your problem persists despite of these suggestions, I'll forward the bug upstream. Keep me informed ! Regards, -- Raphaël Halimi signature.asc Description: OpenPGP digital signature
Bug#829403: tlp: screen flickers every 2-10 seconds
Package: tlp Version: 0.8-1 Severity: important Dear Maintainer, having tlp installed on this Thinkpad T560 makes my screen flicker every few to 10 seconds. It is annoying in a way which makes it unusable. I tried changing the settings to RADEON_POWER_PROFILE_ON_AC=default RADEON_POWER_PROFILE_ON_BAT=default RADEON_DPM_STATE_ON_AC=performance RADEON_DPM_STATE_ON_BAT=performance running tlp start afterwards. It did not change anything. I expect it not to flicker. Thanks for your work and help.
