Classification: openSUSE Product: openSUSE 12.2 Version: Beta 1 Platform: 64bit OS/Version: openSUSE 12.2 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: alex.trevisol@gmail.com QAContact: qa-bugs@suse.de CC: nrickert@ameritech.net, alex.trevisol@gmail.com Depends on: 682528 Found By: Community User Blocker: No +++ This bug was initially created as a clone of Bug #682528 +++ User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:2.0.0) Gecko/20100101 Firefox/4.0 System is a Dell Inspiron N5010 laptop with Intel Arrandale / Ironlake graphics (uses i915 driver). Desktop effects are turned off. With normal active use, everything is fine. But when I let it sit idle for a while, and return to it, I sometimes find it is frozen (no activity, does not respond to ping over the network, requires power off to regain control). Reproducible: Sometimes Steps to Reproduce: System is set at about 50% brightness (I like it that way). The default settings further dim the screen after around 10 minutes of inactivity. If I do something, such as move the mouse, when in that dimmed state, it sometimes brightens to the normal brightness and then instantly freezes. (I have currently turned off that dimming, to reduce the frequency of the problem). There is a forum thread at http://forums.opensuse.org/english/get-technical-help-here/laptop/456110-sys...
