Just tried it, it does not fix it.
Hmmm. I'm sorry but I'm out of ideas. Perhaps its best to either create a new bug report or add yourself to this one: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/934095.
ok, thanks for helping. I guess I could add to that bug report, but it looks like it hasn't been udpated since March.. And it's a different toshiba model.
The weird thing is my brightness works with "Brightness and Lock" but it's just the hotkeys that don't work upon a fresh reboot. It seems it might just be button mapping. But I have no idea how to fix it. I guess next I will try going to Keyboard Shortcuts, and see if the keys register as hotkeys. Maybe I can try to make a script to echo a number in the brightness in /sys/ somewhere..
But even then it would just be a workaround and I would rather get it fixed somehow so I have the brightness bubble that pops up.
Maybe I should try it on my live ubuntu 12.10 flash drive and see if it works there.
I suffered a similar problem on my Toshiba Satellite PRO U500...
I was unable to adjust the brightness at all; I resolved adding acpi_backlight=vendor to the boot line.
I hope this helps
So I am still suffering from this issue.
However, I often use hibernate and [when it works,] suspend, and I have created a script to use in my terminal to change the brightness [using intel_backlight]
I went to Keyboard shortcuts, and my brightness down button [fn+f6] produces the code 0x78, and the brightness up [fn+f7] does not even register as a hotkey.
Can you try the acpi_osi=\"!Windows 2012\" kernel parameter? The relevant line in /etc/default/grub should look like this:
Note the backslash escaping of the quotes.Code:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=\"!Windows 2012\""
