For a Linux Foundation System administration course I just enrolled in, I've tried to install a virtual machine on Arch. I have been trying to install QEMU, but when I follow the instructions to install it on the ArchWiki, but when I run Code: sudo pacman -S qemu-full I get this long list of error messages:

alsamixer doesn't seem to affect the beep (PC speaker) volume in the command line environment - until I launch an X session

Linux Questions - Sat, 07/02/2022 - 19:48
[Arch Linux] The beep sound is very low after booting Arch into the command line. The 'Beep' setting in alsamixer doesn't seem to have any effect to the beep volume in the terminal environment. Only when I startx, the beep volume gets increased to the (audible) level it is set to in alsamixer - and when closing the X session back to the command line the beep stays at that level. But rebooting causes the beep to become quiet again - despite the alsamixer settings getting saved.

I tried a command (in the bash startup script) to set the alsamixer Beep volume at a high amount - it does, but clearly alsamixer simply doesn't have any effect on my command line environment. I'm quite sure once upon a time it worked flawlessly!

Anyone know what's causing it?

Screen resolution limited to 1280x1024x24 on matrox g200e

Linux Questions - Sat, 07/02/2022 - 19:24
I have HP ProLiant ML110 g5 with integrated Matrox G200e graphics card:

Code: 0d:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200e [Pilot] ServerEngines (SEP1) (rev 02) I use it with up to date CentOS 7 and xorg. For some reason screen resolution is limited to 1280x1024 but manyfacturers specification says that it max is 1600x1200x16:

Code: Graphics        32MB shared supporting 1600 x 1200 x 16M resolution under: https://www.hpe.com/psnow/doc/c04282..._lit-psnow-red

I tried to add vga parameter to the kernel during start. With it screen changes for a while to defined screen resolution of 1600x1200 but almost immediately after that switches to 1280x1024.

during this dmesg says:

Solve Apache HTTP POST / Python upload size limitation?

Linux Questions - Sat, 07/02/2022 - 17:41
I am setting up a new server infrastructure and I am running into an upload size limitation with Apache and my Python script which limits files to around 400 MB in size.

I have extensively troubleshooted Apache and it should not be limiting anything. There is nothing relevant in the Apache logs.

Also as far as I can tell Python or anything else is not using too much memory. Top shows plenty of memory left when the upload fails. Increasing the memory allocation from 512 MB to 768 MB did not make a difference.

I am also testing over the LAN and so it should not be network related.

The problem is not browser related because it shows an internal server error when the upload fails. I suppose this is the biggest clue though. There must be a way to read further error information but I cannot see how. If this were a bash script running on the server I would redirect the output to a file for reading later.

Because smaller files transfer successfully it should not be a problem with the script. But I have even tried:
Code: resource.setrlimit(resource.RLIMIT_FSIZE,(999000000,999000000)) to set the maximum file size to 999 Megabytes but there is still the 400 MB limit.

To compound things this is one of those things that cannot be tested locally. The problem is in the interaction between the web server and Python handler script.

What might I be missing?

[SOLVED] python: sys.exit inside a try block

Linux Questions - Sat, 07/02/2022 - 16:57
Did you know that if i call sys.exit(0) inside a try block, the program will cause an exception? Do you consider this a bug?

Code: """
bla bla bla
"""
import sys

try:
    print( "oi" )
    sys.exit(0)
except:
    print( "erro" )
    print( sys.exc_info() )
    sys.exit(1)

print( 'fim?' )

# vim: fileencoding=utf-8: expandtab: shiftwidth=4: tabstop=8: softtabstop=4 The output of this code is:

Code: $ p3 min3.py
oi

(<class 'SystemExit'>, SystemExit(0), <traceback object at 0x7f1160bdd700>)

$ # and exit code of was 1, not 0!

Fluxbox USB keyboard stops responding after disconnect/reconnect

Linux Questions - Sat, 07/02/2022 - 16:31
Hello, LQ. This has been a minor annoyance for a long time. I have searched several times here and using Google and haven't found an answer.

I have multiple computers connected to my monitor on its various inputs, and to share the same keyboard with them I use a 4-port USB switch like this. Switching works fine but when using Fluxbox on this computer and after having switched from/back to it the keyboard works for one keystroke then stops until X is xlosed.

Example: Computer #1 is on button A of the switch and HDMI1 of the monitor. I'm working in an xterm window in Fluxbox, then switch to computer #2 on HDMI2 and push button B to switch the keyboard to it. Few minutes later I return to computer #1 and push button A to return the keyboard and mouse to computer #1. I begin to type something into xterm, and the first letter appears then stops responding - and it does not respond in any other app including the hotkey for the menu and Ctrl+Alt+BkSpc to close X. I have to use the mouse to open the menu and choose Exit to return to the console where the keyboard works again.

The mouse is not connected to the switch as it only takes one input and the other computers don't need a mouse. The keyboard has backlit keys and when it stops responding the backlight is still on; and the caps lock, num lock, and scroll lock keys still toggle their indicators.

As a test I have taken the keyboard off of the switch and plugged it directly into the computer. I then started Fluxbox, unplugged the keyboard, reconnected it, and the same behavior happens. I then tried it on different USB ports and get the same thing. Then I tried a different keyboard without backlight and get the same thing. The mouse does not exibit this behavior.

As another test I tried KDE and XFCE and it does not happen in those DEs. Also, if X is not started it does not happen. Also also, if I boot this computer into Windows it does not happen.

move Debian install from a MSoft VM to a new (actual) machine.

Linux Questions - Sat, 07/02/2022 - 15:44
The title says it all -
I have a working Debian on a MSoft VM, but want to move to a separate private actual physical PC.
Are there any easy ways to do this?

I have seen various posts on moving to a new machine, copy the file systems, etc. but it seems like a lot of the system stuff - partitions, /etc, are system dependent - so do I have to basically start over and install and setup each program and environment?
(I run a web server on the system.)
