description |
The screen brightness controls on this laptop do not work in Ubuntu 10.10 with all updates installed to-date.
Pressing the Fn+arrow keys will bring up the brightness notification and indicate a change, but nothing happens. The power control is unable to dim the screen when switching to battery power or when idle.
There are many other bugs in Launchpad for brightness problems with laptops, but none specifically for the Acer Aspire 5742Z. The similar laptops appear to have other problems I don't have, and fixes suggested in those bugs (nomodeset, acpi_backlight=vendo) do not work on the 5742Z.
Log files attached of various systems:
cat /proc/version_signature > version.log
dmesg > dmesg.log
sudo lspci -vnvn > lspci-vnvn.log
sudo acpidump -o acpidump.txt
sudo acpidump -o acpidump.txt
grep -r . /proc/acpi/video >grep-video.txt |
