http://bugzilla.kernel.org/show_bug.cgi?id=15112 Summary: Radeon KMS on RV250 gets wrong refresh rate. Product: Drivers Version: 2.5 Kernel Version: 2.6.33-rc5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: dri...@ke... ReportedBy: joe...@gm... Regression: No When booting with KMS disabled, the ati UMS xorg driver properly sets the display mode to 1400x1050@60.2hz. xrandr reports the following modes: $ DISPLAY=:0 xrandr Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1400 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1400x1050 60.2*+ 1280x1024 59.9 60.0 1280x960 60.0 59.9 1280x854 59.9 1280x800 59.8 1280x720 59.9 1152x768 59.8 1024x768 60.0 59.9 800x600 60.3 59.9 640x480 59.9 59.4 S-video disconnected (normal left inverted right x axis y axis) However when booting with KMS enabled, all that appears is a black screen. After verifying that fbcon is built into the kernel and that KMS is initializing, I also found that the xserver had started up, but still with a blank screen. After blindly logging in, I ssh'd into the box, and found the following xrandr modes: $ DISPLAY=:0 xrandr Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 4096 x 4096 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1400x1050 60.5 + 60.0* 1280x1024 59.9 60.0 1280x960 60.0 59.9 1280x854 59.9 1280x800 59.8 1280x720 59.9 1152x768 59.8 1024x768 60.0 59.9 800x600 60.3 59.9 848x480 59.7 720x480 59.7 640x480 59.9 59.4 S-video disconnected (normal left inverted right x axis y axis) It appears when using KMS, the correct refresh rate for the 1400x1050 resolution isn't found and instead is a rate that doesn't work with this panel gets setup, resulting in a blank screen. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. |

Switching back to the 1400x1050 mode results in a black screen again. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. |

Does selecting 1400x1050@60.5 with xrandr work? e.g., xrandr --output LVDS --mode 1400x1050 --rate 60.5 -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. |
