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:

Pity it doesn't mention the Pi 400.

[gentoo-user] [OT] Hardware supporting PCIe bifurcation

2021-05-10 Thread Sid Spry 
I can't see an easy way to find this. If you buy a board and look in the
manual sometimes it is there. Searching turns up a few boards that
have the settings exposed but aren't really what I'd want.

Ideally, small AMD board instead of a full sized Intel tower board.

Is anyone aware of a complete list similar to, say, the QEMU one listing
hardware that supports IOMMU groups?

Use is multiple NVMe SSD on a x16 slot without an active switch, among
other things.

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

I decided to apply an ugly hack as a workaround, to allow me to install 
opencv.  Bug report here:

Actually, for video editing, I would at least look at buying a cheaper
PC, and a couple of high-end graphics cards.

Make sure that the software you choose (including linux) can off-load
video operations to the graphics cards, they will provide much better
"bang for your buck" than ram and cpu, in that arena at least ...
