[Ubuntu-x-swat] [Bug 1041790] Re: [snb] GPU lockup IPEHR: 0x0b160001 IPEHR: 0x0b140001, workaround i915.semaphores=0

2013-03-05 Thread Robin Munn
I've been experiencing a recurring lockup that may or may not be this
bug; what I can add to the discussion is that if it is this bug, it
appears to be Linux-only. My company bought several of its developers
identical laptops (Dell Latitude E6520 models). The other developers who
are using these laptops are using Windows, and I'm the only one using
Linux. I've been experiencing these hangups 3-4 times per week, on
average, over the past year. But when I asked the other developers in my
company with Latitude E6520s if they'd experienced random-seeming
hangups, they all said no. Which means that either I got the only laptop
with a defective chip, or else the Windows driver doesn't experience
this problem.

I hope this helps in some way; sorry I can't be of more technical help,
but GPUs are outside my area of expertise.

[Ubuntu-x-swat] [Bug 807347] Re: package fglrx 2:8.861-0ubuntu2 failed to install/upgrade: update-alternatives: error: unable to make /usr/lib/dri/fglrx_dri.so.dpkg-tmp a symlink to /etc/alternatives/

2011-07-13 Thread Robin Munn
I got the same bug on my system that I upgraded from Natty to Oneiric.
The cause turned out to be simple: the /usr/lib/dri directory did not
exist, and so update-alternatives could not create the
/usr/lib/dri/fglrx_dri.so.dpkg-tmp symlink.

Simply running sudo mkdir /usr/lib/dri fixed this problem for me.
