Public bug reported: 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).
