 Posted: Mon Jul 04, 2011 8:28 am Post subject: Gnome terminal text corruption |
 |
|
Has anyone else found that the current Gnome terminal corrupts text?
This is on a 2.38 kernel, and the effect is as if lines of text are overwritten
with a few pixels offset. It doesn't appear over the whole terminal, just
in bands that come and go.
Thanks for any ideas - Will |

Yes, I have the same problem. It started as soon as I upgraded to 2.6.38. Selecting the corrupted lines fixes the corruption until they are unselected, and when e.g. less'ing through a file, it will appear consistently at specific points in the file, but not at all if the file is scrolled one line in either direction. Happens whether compositing is in use or not. Very annoying -- I haven't seen the problem in urxvt or Konsole. The problem happened with both stable =x11-drivers/xf86-video-intel-2.14.0 and ~x86 =x11-drivers/xf86-video-intel-2.15.0-r1.
Sorry to say, I don't have any clue as to the origin of the problem (I was in the process of switching to KDE) but I would like to see this solved. The problem occurred on a x86 stable box, which is now amd64 stable, so I'm reemerging gnome-terminal to see if I can reproduce it. Will report more if so. |

Yup, Intel on-board, 915(?). Thanks for the references - I'll keep an eye on them.

I've got an i915 as well (yay netbook). I just wanted to report that I was able to reproduce the problem, and upgrading to 2.6.39-r4 while keeping with the stable xf86-video-intel-2.14.0 appears to have solved the issue for me  .
Cheers! |

I have a similar problem, but only under 64-bit, and I'm pretty sure I've seen it across kernel and Xorg revisions. I'm guessing the nvidia driver is involved.
Most commands run in gnome-terminal return to the prompt seemingly with no output. But upon pressing return, the output magically appears. It's as if the first time round the terminal forgets the redraw.
I have a similar problem with firefox. Scrolling a web page up or down, very often a small strip of the previous page appears at the top or the bottom of the browser window, depending on the scrolling direction. I tried to take a screenshot, but the corruption disappears as soon as the mouse is moved away from the browser.
So I have two cases, probably related, of redraw failure, but I don't think it's related to the OP's problem. |

Hi Princess Nell,
Can you get a screenshot by running in a terminal:
| Code: | | sleep 60; import -window root foo.png |
to wait a minute while you trigger the corruption, then take a screenshot using ImageMagick's import program? |

| khumba, this method didn't work for me, the resulting image is free of corruption. So I took a picture of the screen and uploaded it here: http://derp.co.uk/09dbe. |
