[bugfix pending] which kernel (mis)config might be the cause ...

... for terminal windows in dwm not refreshing when they change their size (zooming, changing layout etc.). Even when I press Ctrl-L, my terminal windows with mutt, mc and the like somehow seem to keep the dimensions (or seem to think they still have the same dimensions) that they had when they were launched. The funny thing is: It does happen with my custom kernel (zen-git), but doesn't with the stock kernel. yikes

Here's my config.gz: http://pastebin.ch/357

and a screenshot?: 200808032244581280x800sbt7.th.png


Thanks for any hints.
Andreas

PS. I've really tried to find any information about such an issue but didn't succeed. Before I am going to try each and every option (tried a few graphics-related changes already), I thought it would be permissible to ask here if anyone has an idea...

I fail to imagine how this could be kernel related.
Do a diff between the 2 kernel configs and see whats different.

Re: [bugfix pending] which kernel (mis)config might be the cause ...

The diff is rather long (http://pastebin.ch/362) and I'm completely at a loss as to what could be the cause, too.

FWIW, here are the two grub entries:

# (3) Core kernel
title  Core
root   (hd0,2)
kernel /vmlinuz26 showopts root=/dev/sda6 resume=/dev/sda8 vga=791 ro
initrd /kernel26.img

# (4) Zen Test
title  Zen Test
root   (hd0,2)
kernel /vmlinuz26zen showopts root=/dev/sda6 resume=/dev/sda8 vga=791 ro load_modules=off

(That's right, there's no initrd for the zen kernel. But that's another story - the problem is the same if I boot it with an initrd.)

To the OP, I'm having the same problem you have.  I'm using the stock kernel and xterm.

Hm. So maybe not kernel related? But there is no other change in any configuration between my two types of sessions. I have x86_64 with nv x11 driver, dwm 5.1 and xterms. Here's lsmod from the stock kernel session (obviously in the custom kernel there are no modules at all):

Re: [bugfix pending] which kernel (mis)config might be the cause ...

The problem happens with all terminals (tried termit/vte/gnome-terminal (but I think they all are based on vte, i couldn't test urxvt)) and it happens in dwm, openbox and kde - but it's most visible in dwm, whereas in openbox it often helps to hit Ctrl-L, then the layout is repainted with (in most cases) the correct dimensions.
Since it doesn't happen with the stock kernel even in dwm, I didn't test the other terminals/WMs there.

Re: [bugfix pending] which kernel (mis)config might be the cause ...

I've now reconfigured what was kernel26-2.6.25.11 and it seems the config was not the problem: It's working fine, but since stock  kernel26 is 2.6.26(.2), I get the erratic behaviour in stock, too...

Sorry to reply again to myself. It turned out to be a kernel bug:

Now if only I knew how to get me a fixed version... roll
