Public bug reported:
I have dell inspiron 15r 7720 se with core i7
I ve reinstalled 13.10 several times and it doestn seem to work out
properly. So doesnt seem to be my install problem
I havent had such bugs on 12.04 lts version. I havent tried 13.04 .
At first after installation, the brightness slider or adjusting using keys
didnt seem to work. So i did something to make it work.
Ii edited GNU_CMD_LINUX or whatever. its in the askubuntu forums anyways
Now whenever i adjust brightness SOMETIME after boot, the system
freezes.
I think the bug has reduced if i use my system on battery
Or even normally it freezes without adjusting brightness.But mostly on
adjusting brightness this happens
And i cannot install any other ati video driver (in software and updates
app) or the update downloaded from amd ati website. Nothing seems to
work out. If i install those , My system crashes and i cannot boot into
it ever again. Its getting stuck on black screen during boot with X
cursor
to be frank, my laptop is not usable in ubuntu
