I am new to this forum but not to ubuntu ! I have recently installed ubuntu 12.04 on my laptop and I am facing some issues which are as under.
1. There is a random dendency of the system to show a black screen with coding written
2. Firefox 20 version crashes very frequently
3. Chromium web browser also crashes
For problem 1 when the code was displayed i used the shortcut [ctrl+alt+delete] and got logged out and I could use my system once again after logging in. But it helped me only once. I am not sure what is the cause of this problem.
for better diagnosis i am attaching a picture taken from my phone of the screen that appeared the last time.
and please see the 15th last line. call trace??
is that some kind of malware.?
