Just to let you know, I'm preparing an e-petition for legislation to make
all software installation "permissions" voluntary. All software requiring
security permissions should be able to install without those permissions
and run in a limited way, asking again for the permissions when it needs
them and explaining why. Vendors and Network providers will never do this
voluntarily since some of their income is derived from advertisers and
other "agencies" gaining their data in this highly deceptive manner.
I'll let you know when it's up.

They're already voluntary. If you don't like 'em, don't install the app!!



Most of the permissions are required anyway.

Or use an OS that works like that already (e.g. BlackBerry OS).

Also, most versions of Android are so flaw-ridden a malicious app can probably exploit a pre-loaded app to get it to do its dirty work for it.

Okay, getting somewhere now. The problem seems to be graphics card or
graphics driver related.

I switched back to lightdm from gdm, and this time, instead of becoming
completely unresponsive, only the GUI froze, and I could SSH into the
machine. The process /usr/bin/X was using 100% CPU, and the Xorg.0.log
file ends with the lines

[ 14392.979] (WW) NVIDIA(0): WAIT (2, 6, 0x8000, 0x0000bc38, 0x0000bf6c)
[ 14399.967] (WW) NVIDIA(0): WAIT (1, 6, 0x8000, 0x0000bc38, 0x0000bf6c)

[ 14459.162] (WW) NVIDIA(0): WAIT (0, 6, 0x8000, 0x00006ba4, 0x00006ba4)
[ 14462.496] (WW) NVIDIA(0): WAIT (2, 6, 0x8000, 0x00004760, 0x00006638)

I think this is reasonable evidence that something odd is going on
graphics-wise.
