Greetings, |

I spent a chunk of yesterday updating world on my machines (2 file |
| 4 |
servers and 1 netbook) and with some effort, the updates went through. I |
| 5 |
had to go out today so I rebooted my netbook and I started noticing |
| 6 |
weird graphical glitches in certain applications, as if parts of the |
| 7 |
screen weren't updating, namely in urxvt and emacs. In urxvt, my shell |
| 8 |
prompt seems to not render the cursor and often keeps the letters I |
| 9 |
remove still on the prompt (only graphically, they aren't actually |
| 10 |
there). This is extremely annoying. |
| 11 |
|
| 12 |
It's also terrible in emacs: cursor sometimes doesn't get rendered and I |
| 13 |
get tons of artefacts from different buffers when I switch or from text |
| 14 |
I was editing. You can find an example image of such glitches in emacs |
| 15 |
at [1]. This is absolutely tragic for me as I spend majority of my time |
| 16 |
in emacs. I'd like to note that I'm running emacs in a graphical frame |
| 17 |
and not in a terminal. |
| 18 |
|
| 19 |
I'm unsure whether this is the case in my other machines as they are |
| 20 |
headless and don't even have X. |
| 21 |
|
| 22 |
The issue is weird however: firefox and thunderbird are fine, they don't |
| 23 |
suffer any such glitches. I can also make the glitches go away by |
| 24 |
‘refreshing’ my screen with use of xrandr, such as telling xrandr to |
| 25 |
change my settings to what they currently are, which should technically |
| 26 |
be a no-op but well, it seems that it does it anyway. |
| 27 |
|
| 28 |
Oh, I should mention that I did not update my kernel |
| 29 |
Linux misaki 3.9.0-rc6 #1 SMP Tue Apr 9 10:51:07 BST 2013 i686 Intel(R) |
| 30 |
Core(TM)2 Duo CPU L7700 @ 1.80GHz GenuineIntel GNU/Linux |
| 31 |
|
| 32 |
I am truly lost as to how to troubleshoot this. I provide links to some |
| 33 |
of my system information below: |

Please feel free to request any information. I hope someone can aid me |
| 39 |
as this basically renders my shell and emacs useless and they are the |
| 40 |
two things I absolutely need. Even getting my logs was difficult with |
| 41 |
such broken setup. |
| 42 |

Thanks. |
