HD7610M + FGLRX works until shutdown + cold boot.
So I have a Toshiba C855-255 laptop with Radeon HD7610m graphics and I have a problem that I haven't
come across on any forum or google search.
I've had this problem on numerous clean installs and the following happens:
1. I install Ubuntu 14.04.1 on my laptop and reboot.
2. I install all pending updates and reboot.
3. I install fglrx-updates and fglrx-amdcccle-updates and reboot.
(I've tried regular fglrx and fglrx-amdcccle as well. This seems to make no difference to the result.)
4. I reboot and open catalyst control centre (the one with root access) and apply my preferred settings.
5. I can reboot and reboot one after another without any problems. Everything works wonderfully.
6. But then I shutdown and do a cold boot. After I shutdown+cold boot, from now on on every reboot or
cold boot I'll have distorted graphics and I can't read the text very well, but I can login. After login though,
clicking stuff does nothing andthe only thing left for me is ctrl+alt+F2 and uninstall fglrx-updates and
fglrx-amdcccle-updates, so that on the next boot, I use the open source radeon driver again.
This has been the case ever since I bought this laptop a few years ago, so from Ubuntu 12.04 up untill now.
I figured a newer kernel and newer proprietary drivers would eventually fix this, but as far as I've read,
the Radeon HD7610m chip should be working okay with Ubuntu 14.04 and the provided drivers.
I have no deep understanding of hardware and driver software, but seeming everything continues to work,
even on reboots, just not after shutdown+cold boot, maybe certain settings aren't saved properly or at all?
Any help at all or even just finding out why it can't work or if it's brand related would be a big help. I would
like to use the proprietary driver because it just works a lot better with games and since my favorites are
all supported on Linux as of lately, I like to get it to work.
Thanks!
