I upgraded from 13.10 to 14.04 and now after a while the complete OS freezes. I can't even go into TTY1 - TTY6. I have to use REISUB to restart my machine.
Most of the time, it freezes when I use Firefox (Aurora) and play some music videos and surf through the internet. Flash is not installed. Although it also freezes sometimes, when I do not use Firefox at all.
Are there any logs, which are helpful and provide them for you, since the reason for the freeze could be anything at all?
This is my hardware (hope it helps in any way):
- Intel® Core™ i7-3770
- ASUS GTX660TI-DC2-OG-2GD5 (no special driver is installed, just the default one)
- ASUS P8Z77-V LX
- Corsair DIMM 8 GB DDR3-1600 Kit
- Samsung 830series 2,5" 256 GB (Windows is installed here)
- Seagate ST31000524AS 1 TB (3/4 are reserved for files; 1/4 is for Ubuntu (16GB swap included))
Edit 01: Last time it froze, I watched a video and the sound kept playing, so I guess something with my displays; LG IPS235P-BN or my graphic card is wrong?
Edit 02: Seems like there is a problem with my audio settings/setup. If I don't watch any videos/listen to any music, Ubuntu runs like a charm.
When the system froze, I executed these commands from my Android phone:
sudo killall Xorg
sudo killall firefox
sudo killall chrome
But neither of those worked.
The logs from /var/log/syslog can be found here.
The complete kern.log file(1.4GB!) is filled with these 3 lines:
