The bug has come back to bite us for Precise and Quantal since the previous work-around using nvclock/smartdimmer no longer works (see Bug #1039916 "Nvidia driver causing SIGSEGV in nvclock and smartdimmer").
There are better alternatives than the un-maintained nvclock package now, such as Guillaume Zin's "nvidiabl" kernel-module project. However, that fails to have an effect on some Vaio models including VGN-FE41Z. https://github.com/guillaumezin/nvidiabl It would be a good idea to bring nvidiabl into the Ubuntu archives since it uses the existing kernel sysfs interface rather than the hackish nvclock mechanism. ** Summary changed: - no brightness control in sony vaio vgn-fe31b + No backlight control on Sony Vaio VGN-FE31/41 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/115525 Title: No backlight control on Sony Vaio VGN-FE31/41 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/115525/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
