X crashes when screensaver activates
1 Attachment(s)
I'm having an issue with the screensaver activating. It crashes X. It doesn't matter which screensaver I use.
dmesg output is: [ 7258.345115] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. [ 7258.352383] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. [ 7858.357503] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. [ 7858.357510] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. [ 7858.362155] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. [34998.194848] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. [34998.194855] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero. I have an intel 915 chipset I believe. Might anyone know how to fix this? Attached is Xorg.0.log Attachment 6978 |

...those may be harmless. Don't suppose there's anything helpful in Xorg.0.log.old? |

andrew.46, what do you use for a screensaver? Just blank the screen with inactivity?
|
Do other OpenGL programs crash the X server?

I have a 915 chipset and I can recall having similar trouble over the weekend. I'm not one to use screensavers, so I didn't mess around with it too much, but I did notice a few things.
What I know is that I set GLMatrix as my screensaver and went to bed, and in the morning the machine was locked up. I am not going to blame this on the screensaver, as I had several programs running at the time (some of which I had not run before). I also did not get to see if the screensaver started properly and ran for several minutes before crashing. Another curious thing was that there was a preview in xscreensaver-demo, presumably an OpenGL one, that caused X to crash. I am going to try to recreate the crash and then I will report back. |

I have these crashes too on the laptop with an Intel graphics chipset, but only in KDE with compositing enabled and with OpenGL screensavers.
The same screensavers run from XScreensaver in XFCE for example, do not crash. Eric |
