As stated in the title .. after upgrading Ubuntu from 22.04 to 22.04.1 the key combination ALT + TAB is not passed through Citrix Workspace into the Windows Client.
(Citrix is in full screen)
How to fix this ?
In my work Environment we have Windows Clients / Virtual Machines which we connect to via Citrix Workplace.
After some updates on my Ubuntu 20.04 Host - Skype For Business Calls in Citrix get disconnected due to network issues.
In var/log/kern I see this lines - every 20 minutes:
Jan 31 10:55:43 myPcName kernel: [16411.401908] RTMediaEngineSR[14447]: segfault at 10 ip 00007fa8044ae33a sp 00007fa8012f0710 error 4 in libc-2.31.so[7fa8043d3000+1e7000]
At the same time where the SkypeForBusiness Call get disconnected due to network issues.
PS this seems the same issues as in the Linux Mint Forum
Since the virtual disk was too small I resized it via
Oracle VM Virtual Box Manager → File → Virtual Media Manager
After that the Ubuntu 20.04 Guest did not start any more (a short error message I do not remember followed by a blank screen)
I searched for a solution but the things I found looked old or strange to me.
How to fix this easily?
In my host - Ubuntu 20.04 I do have bluetooth in settings.
On the Virtual Box guest however in Settings → Bluetooth it says No Bluetooth found
how to connect bluetooth to the guest?
I try to setup / pair a magic mouse and keyboard with a new Bluetooth stick on my Desktop Ubuntu 20.04.
Unfortunately I do only see Unknown devices and am unable to connect them :/
How to debug / fix this?
Today I upgraded from Ubuntu 16.04 to 18.04 to 20.04
After Login I get the error
Error found when loading /etc/profile:
/etc/profile.d/modules.sh: line 6: usr/share/modules/init/sh: no such file or dicrectory
As a result the session will not be configured correctly.
You should fix the problem as soon as feasible
The code in etc/profile.d/modules.sh is:
shell=$(/usr/bin/basename $(/bin/ps -p $$ -ocomm=))
if [ -f /usr/share/modules/init/$shell ]; then
. /usr/share/modules/init/$shell
else
. /usr/share/modules/init/sh
fi
But
The path /usr/share/modules does not exist

On our home network, I am unable to connect to the wifi in Ubuntu 18.04
How to debug & fix it?
So far I tried:
- Tripple check that the correct password is used (only numbers)
- Connection to other WIFI / WLAN networks is possible (so I assume it is not a general driver issue)
- Verfied the security method
Router / Fritz!Box 6490 :WPA2 (CCMP)
On the Ubuntu Laptop it saysWPA & WPA2 Personal
System Info
- OS : Ubuntu 18.04.2 LTS
- WIFI Hardware: Wireless 8265 / 8275
- WIFI Driver: driverversion=4.15.0-54-generic
In earlier versions ob Ubuntu I could easily change my primary Monitor.
This morning out of a sudden my external Display is the primary monitor. How to change this?
( I do not see any option via Settings -> Devices -> Displays )
At the moment I am unable to connect to a windows file share.
Environment
- System: Ubuntu 18.04.2 LTS
- Mount point is accessible from windows client
I tried via GUI / Files like in the Ubuntu documentation: Browse files on a server or network share:
Files -> Other Location -> enter smb://serverIp/shareName
(The Timeout happens immediately ! )
In the terminal it looks like this:
sudo mount -v -r -t cifs -o username=domain/user,password=myPw //123.123.123.123/share /media/user/share/
mount: /media/user/share/: cannot mount //123.123.123.123/share read-only.

I am not sure why there is so little clear information in the net about the issue:

In order to use an USB-Stick encrypted with Bitlocker I installed Dislocker on my Ubuntu 16.04 according to Use (Windows) BitLocker-encrypted drive on Ubuntu 14.04 LTS.
Unfortunately I cannot decrypt:
sudo fdisk -llists 4 Partitions even though there is only one partition on the USB-stick. And the size is wrong too. (The Disks Utility shows also only one partition.sudo dislocker -r -V /dev/sdb4 -uMyPassword -- /media/bitlockerdoes not mount any of the 4 listed partitions
