When it happens the screen freezes except for the cursor; when I look at a console via ctrl/f2 and wait for a while (about 2 minutes) I see messages like: [20235.667444] nouveau E[plasmashell][16831] fail set_domain [20235.667782] nouveau E[plasmashell][16831] validating bo list [20235.668235] nouveau E[plasmachell][16831] valicate: -22 As soon as these messages appear, the desktop becomes mostly usable, but often strange; the icons become weird and some system messages are corrupted. In a following comment (after I get the desktop back), I will attach a snapshot of the weird desktop and today's journal file. The system is difficult to use with this bug.
