I recently installed Ubuntu GNOME 17.04 x64 with a bootable USB (using rufus).
My laptop is a Dell Insprion 15 5000, i7 up to 3.1 Ghz and a AMD Radeon GPU.
Right after the installation, I had some problems like the whole system freezing after I logged in. Thankfully I fixed this problem by editing one file:
$ sudo nano /etc/default/grub
The problem was solved, everything was working fine until one day when Ubuntu all of a sudden crashed while I was watching a video. I didn't think much about it and restarted, but a few hours later it crashed again.
It looks like this might have something to do with the AMD Radeon GPU again. I checked other posts and website and they said to add something else on GRUB_CMDLINE_LINUX_DEFAULT but I don't know if that will fix the problem or will the previous problem of Ubuntu crashing after login come back.
I also found out that the laptop was getting quite hot. Approx ~10-20 before a crash, I checked the max temperature and it was 78 degree C. So i'm not sure if it could be overheating issues.
Some help would be appreciated :) Thanks!
