Re: display "stretched"

I can't say off hand what is causing it, but if you have access to a "stretched" terminal window, what does xrandr say about the display, and can you use it to return it to the proper size?

Thanks. Yeah, when this happens, I can easily open a terminal. Thanks for the tip. I've just saved the output (I'll print it here, fwiw) so i can compare the next time this happens. And I'll go through the man page to figure out how to (try to) reset the dims.

I find that I generally have to issue 2 commands:

1 to change to a different screen size than xrandr *thinks* is being displayed

and the 2nd to reset the screen back to the size it *should* have been displaying....

I'd really like to know, though, if there's something in a log that might provide a clue as to why it's happening.

Not that I can tell. Some programs play with the display size in different ways. Not all of them are fool-proof (or should I say error-proof?)

Here is my usual example:

I'm running dosbox in full screen mode (80x24 text mode, I think that's 720x480), and dosbox often changes the display mode as well. If everything runs OK, when I exit dosbox, it returns the display to what it was when I started it. Sometimes dosbox hangs. When it does, I have to kill it. Usually it has hosed up X11 in such a way that the only way to kill it is to ctrl-alt-F1 to a console window, and where I do a "killall -9 dosbox" WHen I return to the X11 sessionthe screen size is wrong, but xrandr tells me its 1280x800. Baloney. Its more like 720x480. Typing "xrandr -s 800x600" changes the screen size to 800x600, then I can type "xrandr -s 1280x800" to return it to its proper display size.

I've never found any log files that tell me what went wrong. Not the Xorg.log, not /var/log/messages, nothing I can find....

This is the current output (the screen is fine). I doubt there's anything here to suggest what the problem might be.

$ xrandr
Screen 0: minimum 320 x 240, current 1152 x 864, maximum 1152 x 864
default connected 1152x864+0+0 0mm x 0mm
   1152x864       60.0*
   1024x768       70.0     60.0
   1024x576       60.0
   960x600        60.0
   960x540        60.0
   800x600        60.0     56.0
   768x576        60.0
   720x576        60.0
   856x480        60.0
   800x480        60.0
   720x480        61.0
   640x480        67.0     60.0
   720x400        70.0
   512x384        60.0
   400x300        60.0
   320x240        61.0

yeah, but I'll bet that something else has changed it behind Xorg's back....

Issuing 2 "xrandr -s" commands (like I do) should restore it for you.
