[Bug 40622] New: [radeon] - kms wrong resolution mode used after backlight on/off switch
https://bugzilla.kernel.org/show_bug.cgi?id=40622 Summary: [radeon] - kms wrong resolution mode used after backlight on/off switch Product: Drivers Version: 2.5 Kernel Version: 3.0 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri at kernel-bugs.osdl.org ReportedBy: tkrah at fachschaft.imn.htwk-leipzig.de Regression: Yes Hi, updated to recent 3.0 kernel (oneiric ubuntu build package) and got some behaviour i would not expect. Got a Samsung P35 Notebook - pressing my "backlight" Key does give this in dmesg: keyboard: can't emulate rawmode for keycode 240 On and Off, both a mesage. The native resolution is 1400x1050 of my LVDS Panel. [ 23.577259] [drm] Panel ID String: Samsung LTN150P1-L02 [ 23.577264] [drm] Panel Size 1400x1050 But after pressing backlight twice (off+on) my screen resolution does change to 1600x1024 - afaik not supported, at least it is not mentioned in Xorg.0.log for detected valid panel Modelines. But it does use this mode after backlight switch: (II) RADEON(0): Allocate new frame buffer 1600x1024 stride 1600 I wonder why? However i am forced to switch my resolution back everytime - don't know if its good for the panel to use this resolution (because i don't know if it will blast my panel away i'll set prio to high - if this won't going to happen please set it back to normal ;-) ). Bug or Feature? Both (message and resolution change) did not happen with 2.6.32.x before, so i guess its a regression, is it? Tell me if you need more input or kernel testing. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug.
