Now we have to edit the events to trigger brightness.sh.
Logger "ACPI: AC adapter is off-line, brightness down." Logger "ACPI: AC adapter is on-line, brightness up." If * *//" /proc/acpi/ac_adapter/ACAD/state`" = "on-line" ] This can be used in ACPI events to control the brightness according to the state of the AC adapter.Ĭopy paste the lines below to brightness.sh: You can manually adjust the brightness with setpci: This workaround will not allow you to adjust the brightness with the fn keys.
i'm such a newbie to linux, maybe someone could explain to me why? is it a bug?Īpplying "nomodeset acpi_backlight=vendor" to grub, will crash Xorg, since the most recent version of Xorg doesn’t support this string.įor the T130 I found this workaround, witch will dim the screen brightness and extend the battery time. Hope this could help someone, even though i'm not sure what i am doing. Menuentry “Ubuntu, Linux 2.6.31-14-generic” reboot, it works! both in gnome and KDE! ignoring "DO NOT EDIT THIS FILE", append "nomodeset acpi_backlight=vendor", so the entry changes to: changing in menu.lst has no effect either)
TOSHIBA SATELLITE BRIGHTNESS CONTROL UPDATE
it just doesn't change the \boot\grub\grub.cfg (I found this problem because I can't update Kernel too. Then after a lot of reading I figured out the update-grub doesn't work to me at all. I append that line to the GRUB_CMDLINE_LINUX_DEFAULT there was no effect.
