I installed a X server on Windows 10, I used the WSL and I noticed an issue
# echo $DISPLAY
localhost:0
When I run xclock or xcalc everything works fine, but when I run gitk I get a segfault
~ # xclock
Warning: Cannot convert string "" to type XftFont
~ # gitk
Segmentation fault (core dumped)
~ #
Is there an issue with this?
I'm using OpenSuse Leap 15.1.
Thanks!

I am trying to run gem5 in FS mode by using command as : "build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/coep/gem5%202/full_system_images/aarch32-ubuntu-natty-headless.img --arm=/home/coep/gem5 2/full_system_images/vmlinux.arm.smp.fb.3.2/vmlinux.arm.smp.fb.3.2"
and getting error as : "Usage: fs.py [options] fs.py: error: option --arm-iset: invalid choice: '/home/coep/gem5' (choose from 'arm', 'thumb', 'aarch64')"
please help me to solve this error.
Thank you.
I assume the --arm=/home/coep/gem5...vmlinux.arm.smp.fb.3.2 argument specifies the path to the guest kernel, in which case it should be --kernel=...:
build/ARM/gem5.opt \
configs/example/fs.py \
--disk-image=/home/coep/gem5\ 2/full_system_images/aarch32-ubuntu-natty-headless.img \
--kernel=/home/coep/gem5\ 2/full_system_images/vmlinux.arm.smp.fb.3.2/vmlinux.arm.smp.fb.3.2
Arguments and their explanations are found in configs/common/Options.py
There can be multiple reasons why are getting this error, One of them can be an incorrect path to the disk image files.
I have run the gem5 in the FS mode and have booted Linux on top of it on Ubuntu 18.04 LTS
You can follow the below steps, the first step is to download and install the full-system binary and disk image files.
1. $ mkdir full_system_image
2. $ cd full_system_image/
3. $ wget http://www.m5sim.org/dist/current/arm/aarch-system-2014-10.tar.bz2
4. $ tar jxf aarch-system-2014-10.tar.bz2
5. $ echo "export M5_PATH=/Path to the full_system_image directory/full_system_images/" >> ~/.bashrc
6. $ source ~/.bashrc
7. $ echo $M5_PATH (- check if the path is set correct)
Now the path has been set, the next step is to run the gem5 in FS mode.
1. connect to gem5 base directory
2. $ ./build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/full_system_image/disks/aarch32-ubuntu-natty-headless.img
3. Note: --disk-image=path to the full_system_image/disks/aarch32-ubuntu-natty-headless.img
4. open a new terminal and listen to port 3456
5. $ telnet localhost 3456
6. Here 3456 is a port number on the gem5 terminal
7. this will take around 30 mins depending on the machine performance.
8. After this, at the end you will get something like this
input: AT Raw Set 2 keyboard as /devices/smb.14/motherboard.15/iofpga.17/1c060000.kmi/serio0/input/input0

9. login as root
Voila, you have run the gem5 in FS mode.
I'm trying to get unison working after upgrading to Mac OS X Catalina. Unfortunately, macports installs a more recent version of ocaml (4.08.1), which means that the unison 2.51.2 release won't compile.
Well, that's no problem, I just update to git master on unison, and recompile. Unfortunately, this fails at sync time because the version of ocaml used to compile on the mac (4.08.1) is different from the one used to compile on the other machine (4.07.1). Sigh. Okay, use opam magic to install 4.07.1 on my machine. Everything should be fine, right? No!
Here's the error:
Connected [//zzzmyhost//home/clements/unison-home -> //zzzmyotherhost//Users/clements/clements]
Looking for changes
Uncaught exception Failure("input_value: ill-formed message")

What's going on?
Sigh... the problem here (very non-obvious) is actually with a corrupted/wrong-format syncronization file, created when doing the failed sync in the earlier test.
The solution is just to go into ~/Library/Application Support/Unison (on a UNIX machine this path would presumably live in ~/.unison and delete the archive file that's causing the problem (probably the most recent one). In a pinch, just delete all of the archive files and start over.
I've got the same problem between Windows and Ubuntu 20.04 after upgrading from Ubuntu 18.04. I tried the binary from Ubuntu 18.04 in 20.04, which still fails, so the incompatibility is likely inside one of the dependencies.
As a workaround I created a Docker image based on Ubuntu 18.04:
FROM ubuntu:18.04
RUN apt-get update && apt-get dist-upgrade -y
RUN apt-get install unison -y
RUN useradd martin --home /home/martin
WORKDIR /home/martin
USER martin
Building it with docker build -t unison:18.04 .
And then I added a wrapper to ~/bin/unison-2.48.4-docker:
#!/bin/bash
docker run --rm -i \
-v /home/martin/dirtosync:/home/martin/dirtosync \
-v /home/martin/.unison:/home/martin/.unison \
--hostname $(hostname) \
unison:18.04 unison "$#"
Setting the --hostname is important, since the hostname is part of the archive file.
Inside the profile on my Windows machine I configured:
servercmd = ~/bin/unison-2.48.4-docker
In my setup with two windows clients and one Ubuntu 18.04 server, connected by ssh, the problem startet with a second server running on Ubuntu 20.04. Neither the old server nor the windows clients could sync with the new machine.
My solution: Copying the binary from Ubuntu 18.04 to a new directory in the Ubuntu 20.04 machine. This new file is referenced in the "authorized_keys" file of ssh on the new machine.
So far, everything works great with unison 2.48.4.

this is my script. when i run it i get

what mistake i made. i would be very happy if anybody answer me.
dude, I ran your script and it works fine except the $PGREP ${HTTPD} part, if you want to get a pid why don't you use "pidof" command, and I think in your if statement you are testing the return value of grep, not httpd command(not sure). anyway did you edit this script in word document or in an editor, cause you know this may add some invisible characters to your code.
to debug it, I suggest that you comment out rest of your code where you get the first error and see figure out the solution to that specific error.

While on the same time FireFox managed to get the page correctly

Any help will be appreciated,

Have you tried running the script through proxychains? To install on ubuntu:
:~$ sudo apt-get install proxychains
then configure the /etc/proxychains.conf file to work with TOR (socks4/5).
# defaults set to "tor"
socks4 127.0.0.1 9050
Then you can run anything though TOR
:~$ proxychains scriptwhatever.py target
Once you know TOR is working correctly, I recommend quiet mode in the proxychains.conf file.
# Quiet mode (no output from library).

I am using the default Apache installation that comes with Snow Leopard and I have some things installed like MySQL, Rudix (Unix ports and packages) and Xcode.
When I type:
$ sudo apachectl start
I receive this output:
dyld: Symbol not found: _apr_dir_open$INODE64
Referenced from: /usr/local/sbin/httpd
Expected in: /usr/local/lib/libapr-1.0.dylib
in /usr/local/sbin/httpd
/usr/local/sbin/apachectl: line 78: 2023 Trace/BPT trap $HTTPD -k $ARGV
I don't know if it's related but my .bash_profile has this line (I typed it because import MySQLdb was not working in Python):
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH"
If I tick Web Sharing using System Preferences the Apache starts and work, but I wan't to start it using the terminal, maybe I am forgot to pass important arguments to the apachectl command.
The Web Sharing option of System Preferences enables the Apple-supplied Apache. Its apachectl is /usr/sbin/apachectl. You appear to have installed another version of Apache in /usr/local; note the /usr/local/sbin/apachectl path. So you are not using the Apple-supplied Apache installation when you are running from the terminal and the version you are using appears to not have been installed correctly. One way to ensure you are using the Apple-supplied Apache is to specify the full path:
$ sudo /usr/sbin/apachectl start
