Okay...lemme start by noting that I'm not adept at linux. At all. But running in a problem like this is IMHO a good way to actually learn something (and this is on a test machine, so it's not like there's really anything worth it on the HD). So I was testing out a game both on linux (mint 18) on wine and the other partition: windows 7. Noticed it ran noticeably slower on the former, which is something that can happen when running wine. In poking around, I came across this guy on a forum who said I could try with gallium nine drivers (that may offer better performance on directx 9 games). So after a quick google, I found this guide. Seemed simple enough at first: add a repository, download the drivers, configure it in wine and done. That's where things started going wrong. Though the install seemed to work okay, the option to patch wine to use said drivers wasn't there -> wine wasn't patched. :-\ Then, after a reboot, cinnamon acted up. Or rather: pretty much every program acted up. Figuring that was the only thing that was changed, I decided to backpedal the gallium drivers out of there (ey...they were experimental in the first place ). Unfortunately...during the uninstallation scripts, I noticed that it did quite some more uninstalling than it installed earlier. I sat it out until the end because a partially uninstall of something critical is probably worse than a finished one, I let it finish. And sure enough: after a reboot, the screen stays blank. Hmm...not so good. Getting in the mint command prompt isn't so hard...but finding the right commands to get or install the correct drivers is something I just can't find. Anything I try seems to result in...well...just the same command prompt I had earlier. Or a black screen if I attempt to boot the normal way. So hence this thread: does anyone know how to restore this mess I created myself? (note: if I don't have an answer in a week, I'll just reinstall mint from scratch. As said: this is a test laptop).
