If I browse to comics.com using konqueror under KDE on Fedora 11, X will, after a delay, lock up. The mouse will move, but no keyboard input is recognized, and the screen does not react to the mouse passing over objects on screen. I am able to ssh into the machine and issue shutdown -r now and have that work. The machine is a Dell XPS M1330 with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c), and Fedora 11 is fully updated. Visiting the same site in Firefox does not cause a lockup. I am booting with nomodeset since it won't boot into X otherwise. I tried the other two accel options: EXA (still locks up) and XAA (X won't start). Any suggestions on how I can debug this? bugzilla
