280.11: 100% CPU and hung gnome-session
1 Attachment(s)
1. type username and password at gdm login window
2. gdm login window disappears but nothing happens
3. CPU Fan starts going at max speed

Switching to VT, and using top shows gnome-session is eating 100% CPU.
However perf top shows that all the time is spent in nvidia-driver:


  PerfTop:    1001 irqs/sec  kernel: 2.5%  exact:  0.0% [1000Hz cycles],  (all, 1 CPU)

I'm using GNOME3, and it happens logging in as either "gnome-shell mode" or "fallback mode".

EDIT: I forgot to mention that 280.04 works fine.

[bug report] 275.19 makes Gtk apps go into infinite loop when quitting, breaks Gnome

The (apparently) same bug is triggered by Clementine. Latest nVidia driver hits an infinite loop:

Thanks for reporting this. I filed bug 858349.

From this gentoo bug I've found that compiling the cairo library without opengl support fixes the problem

Re: 280.11: 100% CPU and hung gnome-session
I can confirm this as well (can't even login via gdm... I enter username & passwd and the screen just goes to the gdm background while xserver eats an entire core...)

275.09.07 work well for me.

280.13 & 285.03 have this issue.

What is more worrying is with this new "long-lived" driver program (ie 275.28) which is just suppose to have bugfixes has this EXACT same issue.

Thus one of these so call bugfixes has the regression
