Taskbar disappeared!
 

Hi all!

Just coming back from work and my taskbar is nowhere to be found. Is there a way to bring it back up without logging out? I am runnin kde - FC2.

As always thanks for any help!

PS - This is what I got from /var/log/messages from today - are those DHCP requests normal or someone gained access to my comp?

Just go ahead and log out.

If that doesn't work, restart KDE.

If that still doesn't work, you may need to hand edit a KDE config file somewhere.

For SUSE, you right click on the desktop, and you chose the option to run a command. Type "kicker" without quotes and this starts up the taskbar again. Dunno it FC2 has such an option when you right click.

Yes it dows. It's the same for KDE in all distros. Alt+F2 ---> graphical command line opens ----> enter "kicker" and voila!

Thank you - its back on!!!!!!!

here's the kicker
 

I had the same problem with my task bar. When I tried to restart it the error message I got was 'kicker is currently running'. I thought WTH? Then by accident I hit ALT+F1 after reading other fixes and using ALT+F2 to bring up the run command window. So apparently I have subconsciously hidden my task bar several times. I believe my task bar hides when I'm closing multiple apps. because when I'm done the task bar was playing hide n' seek.

this worked for me:
go to the terminal and write

kquitapp plasma

and now write:

plasma

rassbery pi 3
 

I have a rassbery pi 3 and I tried "kicker", but it it has an error saying it is not a command. I also tried rebooting. My taskbar dissapeard when I changed the font size. What do I do?

Are you definitely using KDE?

Yes, I pressed alt F2 after clicking on the desktop. It is titled as run.

Also my browser randomly closes itself.

Welcome to LQ, 24k9robot.

Can you please start a new thread in the Linux-Newbies forum and provide more info on your system, your distro and the actual errors you encountered.

Necroing two old threads on the subject at the same time is not recommended.

I do not have a task bar. I have a rassbery pi 3 and I tried "kicker", but it it has an error saying it is not a command. I also tried rebooting. My taskbar dissapeard when I changed the font size. My operating system is NOOBS. Also my browser randomly closes itself.

Did you enable swap? You're probably low on RAM and things go bye when that happens. Otherwise try tint2, a taskbar that you can add to wm's that don't have task bars. Perhaps good enough to get you an xterm so you can take a look around and figure out what ails you.

How do I enable swap? Also I haven't had a taskbar for about 3 days now and I tried rebooting at least twelve times. Luckily I put the logout button on the desktop. Please help me.

You can Control+Alt+F# to switch to other TTYs, aka non-gui consoles / terminals (depending on distro / init system). From there you can run tint2 or enable swap. One of the Control+Alt+F#'s should get you back the gui, used to be F7, now probably F1. Once on the non-gui variant, you can use Control+Alt+F#, but Alt+F# also works. From the gui you need all the keys.

$ export DISPLAY=:0; tint2 &

$ sudo dd if=/dev/zero of=/SWAP.swap bs=1M count=1000
$ sudo mkswap -v1 /SWAP.swap
$ sudo swapon /SWAP.swap

Creates a 1GB file, formats it for swap, and enables it. Once created, you only need to do that last one to enable it after boot, or add it to /etc/fstab and reboot to automate that process.

$ sudo swapon -s
$ free

To see that swap is there. It's ram as a FILE and a file that is a filesystem on a filesystem. Which is super slow compared to RAM, so you'll probably be aware of when you're using it. Beyond querying the statistics. But it should make things more stable if RAM is why it's having issues.

TBH, for issues like this, a fresh install can often prove the faster solution than trying to figure out what went wrong.

I did that and it said "export DISPLAY=:0; tint2 is not a command.

You would have to install it for it to work.

$ sudo apt-get install tint2

Is the kde - fc2, the version the came with fedora core 2 (like a decade ago or more)? What ever YUM method applies, if so. Although tint2 might not have existed way back then.

If you don't have to much customization done to KDE, you could try removing the $HOME/.kde stuff or $HOME/.config/kde stuff and restarting KDE / rebooting. Perhaps backup that first or rename them, so you can compare to what regenerates and ID what thing changed and what KDE called that thing. Or create a new user and have it start KDE to see if it's not an issue for a new user, then diff the configs. I would assume that there's some right mouse -> prefs or properties type option to toggle something like that (or will be someday).
