Xubuntu 14.04 freezing and crashing randomly

[gabriel19]

I have just installed Xubuntu 14.04 and it's constantly crashing just like the pic shows and I have to reboot. Could you tell me what's happening and possible solutions? I'm new to the system. Thanks.

can you tell us what graphics card and driver you're using please? you can issue the following command and look for the line that has "VGA" in it (i think)


sudo lspci -v

It says:

It usually happens after I launch an application, especially after I click on the mail notification and firefox but also the file manager.

Ok, you have an nvidia card and are using the default nvidia open source driver. may i suggest trying out the proprietary nvidia driver, look within settings, additional drivers. it appears like a graphics driver problem but it may be related to something else, who really knows. good luck
