Today I again updated zorin & kernel updated too.. last figure i remember is 45..i dont have nvidia nor radeon gpu.. just intel pentium dual core t2310 processor. . it is compaq pressario c707tu laptop with increased 2gb ram..graphics is intel 965gm & zorin os9 64bit..
Now it is not sometime going to black Screen but almost evertime goes black Screen while surfing.. google chrome is running better than firefox but at some stage, both make black display. . also i purge openjdk-7-* from running command on net as i want to install oracle jdk8. i don't whatever creates the problem. . can i send any log to you.. please tell me how to send log.. i have zorin 9 on pc running fine.. its just latop that create problems..

update:
i think its not the vbrowsers problem..i played you tube video and this happens..the music still playing...i typed ALT+CTRL+F2 and music stops..then pressing alt +ctrl+f7 resume it..shells working right..then i closed the lit and open it display resume..it may not be browser problem i guess but some system app. how do i identify it..plz help.
Thanks

Hi,

how you did you install your system as I think it is something to do with the way you installed your system?:

Did you follow the tips in the above link?.

You can try running the following terminal command (Ctrl + Alt + t) and hope that it fixes the problem for you:

Code:

sudo apt-get update && sudo apt-get dist-upgrade -f

RESTART AFTER RUNNING THE ABOVE COMMAND!.

Let us know how you get on.
