I installed ubuntu (12.04.04 LTS, 64 bit) on a laptop Dell Inspiron 3537. It's working great. Recently, I had some trouble with running applications through wine. Those problems were resolved once I installed some additional drivers.
The problem is, when going to System Settings > Additional Drivers, the only option there is this:
While this did fix my earlier problems with the wine applications, I'm now facing new problems - every time I close the lid, when I open it up again I see a black screen and only the mouse (but I can't move it). The computer doesn't respond to anything I do, and I have to forcibly shut it down and start again.
If I leave the computer open, and it goes to sleep, then this problem doesn't happen. I'm guessing this has to do with the driver being "experimental" and all, though I haven't faced any other major issue since installing. I would change the driver to a non-experimental one, but as you can see from the image, ubuntu isn't offering any alternative.
running the command lspci | grep VGA returns this output:
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8800M Series]
Any ideas what I should do ry?
update
I just installed the earlier non-experimental video drivers through synaptic and after rebooting, the problem still persists. What's the problem here?
update2
Alright, so I did two things. First, I followed these instructions, and after a failed resume and reboot I created a dmesg.txt file, which contained three mentions of hash matches:
[ 1.766773] Magic number: 0:665:273
[ 1.766776] hash matches /build/buildd/linux-lts-saucy-3.11.0/drivers/base/power/main.c:643
[ 1.766798] tty tty10: hash matches
[ 1.766804] net lo: hash matches
Second thing I did was run the command dmesg | grep fglrx, which returned this:
[ 12.203459] fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.

I'm thinking the fglrx: module verification failed: signature and/or required key missing is the important part. Any ideas how to solve it?
