Title:
Toshiba Portege R830-13C no backlight after resume from suspend
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Toshiba Portege R830-13C: laptop comes back from suspend, but with no
backlight.
I can slightly work around it with the script at
http://www.refreshit.info/2013/03/solved-backlight-problem-after-
suspend.html , but this is less than ideal (and I can't adjust the
backlight after this).
uname -a output:
Linux lt14000 3.8.0-14-generic #24-Ubuntu SMP Fri Mar 22 19:45:03 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
This is a regression from Quantal on the same laptop, where the
backlight came back after suspend - stuck at full brightness, not
adjustable (so still not 100% functional).
[Extra information for backlight bugs will be added next.]
