Hi all,

I just recently setup a new desktop with Gentoo.

After the install and configuration of Xorg, I decided to 'startx' and open xterm in fvwm.

Upon pressing the button to launch it, nothing came up. When closing fvwm, I saw the following message being printed ad nauseam to the screen:

open ttydev: I/O error

Online searches led me to inconclusive info on what could be the cause and fix for the issue.

I'd be glad to provide info as required.

Best regards,

vhns

No idea what's the cause, but I had success with a small script contain-
ing:

fvwm --replace &
while sleep 1 && ! ps -efu rainer | grep FvwmIconMan | grep -qv grep
do :
done
sleep 1
xterm -geometry 80x40+0+0 -xrm "*Page:0 0 0" &

This script is in turn started upon login via Xfce's "Application Auto-
start" tab of the "Settings -> Session and Startup" menu. If you don't
start "FvwmIconMan" in your "~/.fvwm/config" file, replace it in the ab-
ove "grep" command with a module you do start.

Hope that helps.

Sincerely,
Rainer

Hi all,


I've decided to try another terminal emulator, in order to figure out whether this was an xterm issue, an issue with my setup, or an issue with fvwm.

Launching (or trying to, rather) x11-terms/st, gives me the following error in dmesg:

[May10 21:17] traps: st[5846] general protection fault ip:7f92d0babff6 sp:7fffa63836a8 error:0 in libc.so[7f92d0b97000+63000]

I am not sure of what may be causing this, or how to fix it. Here follows my emerge --info:

I see lots of references to "musl", which I assume you're using.
I wonder if there's an incompatability somewhere there.

Ok, the "segfault" errors were due to a faulty stick. Now replaced. I rebuilt every package in the system. I no longer get segfaults. But I still get the same message in xterm and st throws no errors but just like xterm it doesn't open.
