Der bookworm-Kernel macht Probleme beim Resume.
Abhilfe: bookworm-backports-Kernel 6.4 installieren.

apt install -t bookworm-backports linux-image-amd64

Swappiness is 60 by default which is fine in most cases. But if you decrease this number, your system will use RAM more and start writing to Swap much later. Swap is an actual disk space and it is much slower than RAM. If you have 8G or more of RAM, you can force your system to use it at maximum.

First, check your swappiness value:

cat /proc/sys/vm/swappiness

Open the /etc/sysctl.conf file with Vim and add vm.swappiness = 10 at the very end.

ssh springm@hermes

sudo su
echo "restic --no-lock -p /root/resticpw -r /backupdisk/restic-repo mount /resticrestore" | at now
cd /resticrestore/hosts/kudell/latest
tar cjf /tmp/kudellroot.tg2 root
tar cjf /tmp/kudelletc.tg2
tar cjf /tmp/kudellspringmssh.tg2 home/springm/.ssh

Auf kudell:

scp springm@hermes:/tmp/kudell*2 /tmp
mv ~springm/.ssh ~springm/.ssh.old
cd /tmp
tar xjf kudellroot.tg2
mv /root /root.old
mv root /

Damit sind die alten ssh-keys wieder intakt.

from: https://unix.stackexchange.com/questions/3505/how-to-install-adobe-acrobat-reader-in-debian

NOTE: The 9.x branch of reader has been EOL'd as of June 26, 2013. If you need native Adobe Reader support on Linux, 9.x is your only option! 10 doesn't list Linux as being supported, and likely never will. More on it too here: Adobe abandons Linux.

wget ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/AdbeRdr9.5.5-1_i386linux_enu.deb

After doing this we should have the file, AdbeRdr9.5.5-1_i386linux_enu.deb. Now we're ready to install it.

The file we just downloaded is the 32-bit version of Adobe Reader. Adobe only provides Reader as a 32-bit binary, there is no 64-bit variant, but this is perfectly fine, we just need to install it a bit differently than most .deb packages.

First we need to add the 32-bit architecture to our system (multiarch), then update.

sudo dpkg --add-architecture i386
sudo apt-get update

Now attempt to install Adobe Reader with either dpkg and apt-get OR gdebi. If you pick the first option, it will require you to tell apt-get to fix any broken installed packages. This would seem to be a hack, but it basically gets apt to do the heavy lifting for us and install/fix any missing or broken packages with relatively little fuss. Alternatively, using the second method, gdebi will automatically resolve the dependencies.

sudo dpkg -i AdbeRdr9.5.5-1_i386linux_enu.deb
sudo apt-get install -f

Now, attempting to launch acroread with

acroread

gives

/opt/Adobe/Reader9/Reader/intellinux/bin/acroread: error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory

Adobe forgot a dependency. We can figure out which package to install using apt-file.

apt-file search libxml2.so.2

which gives libxml2. So we do

apt-get install libxml2:i386

to install the i386 version of libxml2.

For anyone who is using Ubuntu 18 (to give you the same behavior as e.g. on Windows10):

• go to settings > devices > keyboard
• look for the keyboard shortcut for “Switch windows”
• set this to the shortcut Alt+Tab (this will overwrite the old shortcut)

Sound funktioniert über die XONAR SE Soundkarte, Subwoofer läuft nicht am Subwoofer-Ausgang :(
Abhilfe: Subwoofer an den Rear-Port anschließen
