Running issues with BadShmSeq after following FAQ

[likelydo]

Hi all,

I am very new to this and followed this post to install seq. I started with installing Ubuntu 18.04.6 LTS (WSL) to windows 11 (as opposed to installing Linux Mint 19). Then went through all the steps in the post without any error until the launch of showeq. I got the BadShmSeg error. Did the trick from the FAQ as following but still the same error.

cd /usr/local/bin
export QT_X11_NO_MITSHM=1
sudo ./showeq

I am running EQ using the build-in wifi from motherboard. There are 2 network interface "eth0" and "lo". Both gave me the same error.
Hope anyone can shed some light on this. I think i am missing something here. Thanks!

I've never tried to run ShowEQ under WSL, so I have no idea how well it works in general. That said...

You're doing your export as your user, and then doing sudo ./showeq to run as root. I don't know how 18.04 has its sudo configured off the top of my head, but it's very likely that your user's environment is not getting passed to root when you sudo to run showeq, meaning that env var isn't actually getting set in a way that SEQ can use it.

If this is the case, then you'll either need to adjust your sudo config (see man 5 sudoers, particularly the parts on env_reset, env_check, env_keep) so that QT_X11_NO_MITSHM gets passed in, or you'll need to sudo/su to a shell, then as root do the export and run showeq.

The latter should be as easy as

$ sudo -s
# cd /usr/local/bin
# export QT_X11_NO_MITSHM=1
# ./showeq

thanks for insight! I think I got it working doing a sudo first

sudo QT_X11_NO_MITSHM=1 ./showeq

He beat me to it. I was going to say it looks like a permission problem. ShowEQ needs root access. Congrats on getting running.
