 Posted: Sun Dec 30, 2018 2:51 pm Post subject: [RESOLVED] LV2_PATH not set |
 |
|
Hi all,
I noted that since several months the environment variable LV2_PATH is not set by default. Therefore I manually put a file named "60lv2" in /etc/env.d . Permissions and owner should be fine:
| Code: |
# ls -l 60lv2
-rw-r--r-- 1 root root 24 28. Dez 00:49 60lv2
|
[/quote]
In this file I added the line
| Code: |
LV2_PATH=/usr/lib64/lv2
|
However after every reboot
results in an empty variable.
Only after manually executing
| Code: |
source /etc/profile
|
the variable is set to the value above. What am I doing wrong?
I also checked the contents of /etc/profile.env. I contains the line
| Code: |
export LV2_PATH='/usr/lib64/lv2'
|
the link /etc/make.profile points to
| Code: |
/etc/make.profile -> ../usr/portage/profiles/default/linux/amd64/17.0/desktop
|
Thanks for your help.

How exactly do you log in after a reboot? Does your machine boot to a login prompt on a console? Or does it boot to a (graphical) login manager? Which one?
Which shell do you use? Bash?
Please note that bash can be invoked in different modes (interactive login shell, interactive non-login shell, non-interactive shell, ...). Bash executes commands in /etc/profile ONLY if it is invoked as an interactive login shell, or as a non-interactive shell with the --login option. Look at 'man bash', section INVOCATION for details.
Some login managers seem to start the first bash shell after a user logs in NOT as a login shell. Consequently, /etc/profile won't get executed and the user won't have the environment defined in /etc/profile. |

I'm using lightdm as login manager and cinnamon as desktop environment. Usually I'm using the xfce4-terminal with bash. But for the LV2_PATH variable it doesn't seem to matter. E.g. if I start ardour5 using the cinnamon start menu, it becomes clear that LV2_PATH isn't set either.
However, your explanation pointed into the right direction and helped me to find the culprit.
After login in a virtual console (e.g. Ctrl+Alt+F1) I found that the LV2_PATH is set correctly.
/etc/lightdm/lightdm.conf has the following line calling the wrapper script Xsession.
| Code: | | session-wrapper=/etc/lightdm/Xsession |
And this wrapper script should set the variables. It contains:
| Code: |
# Load profile
for file in "/etc/profile" "$HOME/.profile" "/etc/xprofile" "$HOME/.xprofile"; do
if [ -f "$file" ]; then
echo "Loading profile from $file";
. "$file"
fi
done
|
However, it also executed another script I had on my system:
/etc/X11/xinit/xinitrc.d/61cadence-session-inject
This file contained
| Code: |
export LV2_PATH="`$INSTALL_PREFIX/bin/cadence-session-start --printLV2_PATH`"
|
After deleting this file, LV2_PATH is set correctly again.
Thanks for your help! |
