In Fluxbox trying to cli a text editor and file and no go x org error.

Trying to get ma' thumbnailer working, it is not producing thumbnails for mp4 movies. So when I went to open up the file for it to take a look see, I got this instead of the application opening the file. Both Kwrite, and greany.

Fluxbox

Code:

(userx@slacko⚡️~)>>$ sudo kwrite /usr/share/thumbnailers/pcmanfm.thumbnailer
No protocol specified
kwrite: cannot connect to X server :0
(userx@slacko⚡️~)>>$ sudo geany  /usr/share/thumbnailers/pcmanfm.thumbnailer
No protocol specified
Geany: cannot open display

what more info needed, I will get it.

regarding the other issue you got, FYI, to have video thumbnail in pcmanfm you need ffmpegthumbnailer: note that, like written in the README, "supported videoformats depend on the configuration flags of [its dependency] ffmpeg".

installed already -- ffmpegthumbnailer -- that is why I was investigating the pcmanfm.thumbnailer file ..

This does work in Void Linux, I had it working in here once,
Thanks though.. though I might have to check which one I installed, it was a while ago... it is one of them little things that need to be fixed to get it working (again). I'm just getting around to it.

I fix this problem due to .Xauthority

Quote:

Eventually, run the following command as the user that you want to get access with, on the server:

xauth info

This will show the 'Authority file' that will be used (/root/.Xauthority by default, for root, or something like /home/theuser/.Xauthority). If it shows the correct .Xauthority file then you don't have to worry about the XAUTHORITY environment variable actually (actually, I wouldn't know when it wouldn't, except if you want to manipulate a non-standard place of that file).

Remove that file (if it even exists):

rm /root/.Xauthority

Replace /root/.Xauthority with the correct XAUTHORITY file for your case.

Recreate it, but empty (this is needed for a lot of commands):

touch /root/.Xauthority

At this point you'll get the No protocol specified error, even if you got Invalid MIT-MAGIC-COOKIE-1 before. Find the authority file that the X server is using at the moment:

ps aux | grep Xorg

This should show something like:

root 1153 0.0 1.0 149560 44464 tty7 Ss+ dec02 0:00 /usr/lib/xorg/Xorg -nolisten tcp -auth /var/run/sddm/{ef18c483-7891-4e82-80ef-2c8f9bd79711} -background none -noreset -displayfd 17 vt7

The file name after -auth is what you need in the next command. Run this as root:

sudo xauth -f '/var/run/sddm/{ef18c483-7891-4e82-80ef-2c8f9bd79711}' list

That lists a 32 digit hexadecimal key. For example the output could be:

hostname/unix:0 MIT-MAGIC-COOKIE-1 c0eaf749aa252101a0f57d5087089db7

Use that to generate your .Xauthority file (as user who needs to login again):

xauth add $DISPLAY MIT-MAGIC-COOKIE-1 c0eaf749aa252101a0f57d5087089db7

replace 'c0eaf749aa252101a0f57d5087089db7' with what was returned by the list command for you. Now your .Xauthority should be size 51 bytes and you can connect to the X server (again).

Haha like I thought, it was just one of them little things missing like, ffmpeg itself .. lol fixed that too..

BW-userx · 01-30-2017, 10:09 AM

rebooted then tried it again and got this...

Code:

(userx@slacko⚡️~)>>$ sudo kwrite &
[1] 31933
(userx@slacko⚡️~)>>$ Invalid MIT-MAGIC-COOKIE-1 keykwrite: cannot connect to X server :0
^C
[1]+  Exit 1                  sudo kwrite
(userx@slacko⚡️~)>>$ sudo geany
Invalid MIT-MAGIC-COOKIE-1 keyGeany: cannot open display

so that fix I posted didn't permanently work

Don't run GUI apps as root. They simply weren't designed for it.
A better workflow would be:

Code:

cp /somewhere/somefile /tmp
kwrite /tmp/somefile
# And if you want to put the changes back...
sudo cp /tmp/somefile /somewhere/somefile

mmmm

even /tmp requires root priv yes?

but I do get your methodology

sudo nano /etc/somefile ???

well Slack does do somethings differently

thanks

If you really want to run GUI apps as root (which most of the time, there shouldn't be a reason for it, but it can happen occasionally), you can use kdesu, which is included in a full Slackware install (it is obviously part of KDE), or you could get gksu from SBo. This will set the environment correctly and shouldn't affect permissions in your regular user's home folder (which is a common issue when using su or sudo for GUI apps).

Like you said on occasions. Mostly I use nano but yeah I just like working with a gui when the file maybe big or copy paste mab required, (ooh I know that already, got a be careful with copy paste).

But there was an incident not long ago when I was having problems with my clock no syncing with my other distro, had I copy pasted instead of relying on my finders. they took a break and the word never got finished being completely typed out. Due to my fingers not doing what they should have when my brain did. the time wasn't being set properly. that being said on copy paste.

yeah GUI, It is easier to scroll down and for me to do things to it. especially with a desktop file, I'll chop out all of that non needed added defs to shorten it up.

I'm just use to running sudo program name - edit - save - done.

kdesu in fluxbox
gksu I've used before.
got a get / change habits I suppose.

thanks
