Thread: Too dim screen on laptop lid opening

hi all,

having issues dim screen after re-opening acer e1 531 laptop. running ubuntu 12.10. seems if screen goes sleep on it's own, good, if close lid seems issue. can see screen when happens, , there seems no way brighten it.

have tried disable 'dim screen save energy' settings, have seen recommended, not work, found https://wiki.ubuntu.com/x/troubleshooting/blankscreen. however, new may need me through steps.

if appreciated.

cheers

i having exact same problem on kubuntu, although have found temporary work-around.

because kubuntu uses kde , ubuntu doesn't may have differently pretty do:
- open system settings
- go power settings
- change apply button lights up
- press apply

i'm pretty sure works differently on unity, maybe this'll help.

think problem comes fact computer "forgets" set brightness previous value. changing settings forces reset brightness whatever have in settings (you don't have change of setting's values, saves "changes"). it's pain after every time close , open laptop lid works.

edit: might have misunderstood you. problem screen brightness becomes dim, not turn off.
oops.
