X not working on upgrade from Ubuntu 10.04 on a Samsung Q45 Platform: - Samsung Q45
- Ubuntu 10.10 Maverick
- Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller
- Integrated Graphics Chipset: Intel(R) 965GM
- Kernel driver: i915
Issue: - After upgrading from 9.10, X doesn't start any more.
- /var/log/Xorg.0.log says:
(EE) intel(0): No kernel modesetting driver detected. (EE) Screen(s) found, but none have a usable configuration.
Cause: unknown Solution: - Edit the file /etc/default/grub and add
GRUB_CMDLINE_LINUX="i915.modeset=1" - Issue update-grub
- Reboot
Fn+brightness keys do not work UNRESOLVED draft
Platform: - Samsung Q45
- Ubuntu 10.10 Maverick
- Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller
- Integrated Graphics Chipset: Intel(R) 965GM
- Kernel driver: i915
Issue: - Some Fn-keys (brightness) do not work
- The Samsung Q45 does not send key release events for several Fn-keys.
Cause: Samsung bios bug Solution: As the Q45 uses the same keycodes as the NC10, I extended the fix
with the DMI information of my Q45, which works great on my machine, and
finally lets the lcd brightness be adjusted via Fn-keys. - Add "acpi_backlight=vendor" option as GRUB_CMDLINE_LINUX in /etc/default/grub
- Issue update-grub
- Reboot
