I am using VLC 4.0.0 on Ubuntu 20.04. I want to play a video on my Chromecast 3. However, when I open the renderer menu it appears empty -- not even "Local", one option I had before upgrading to Ubuntu 20.04. See image below.
How can I get VLC to search for my Chromecast, so I can cast video?
Second edit: Since this question keeps getting attention, I want to put a clear disclaimer at the top: if you are experiencing this problem, it will likely be solved by pressing and holding the left-most and right-most button on your pad at the same time for a few seconds. You will notice that it has worked when the light at the top gets brighter. Avoid messing with anything else until you have tried this solution. Reinstalling drivers can make the problem worse.
The original title of this question was "Only left half of Wacom Intuos S is working". The text of the original question preserved below. I have since figured out part of the problem, so I am updating this question.
I am using a Wacom Intuos S on Ubuntu 18.04. If I plug it into the laptop, the device automatically goes into Android mode. This is a known issue with Ubuntu. This is confirmed by the output of libwacom-list-local-devices (output shown in the original question) as well as the output of lsusb which lists the vendor ID of the device as 2d1f (as noted in the link above on the issue). The tablet then behaves erratically.
I can toggle the pad to PC mode by holding the leftmost and rightmost button for a few seconds. The tablet then seems to successfully switch to PC mode: lsusb recognizes the device, the vendor ID updates to the correct value, and the indicator light turns on more brightly. However, now the device does not work at all: the cursor does not respond to the movement of the stylus, it is not recognised by Settings (gnome-control-center), and libwacom-list-local-devices does not list it at all. xsetwacom --list devices also comes up empty.
On my home laptop (very similar to my work laptop) switching the pad to PC mode fixes the issue: I can use the tablet without changing anything or updating any drivers. This is also true for a colleague, who was struggling with exactly the same issue (also on Ubuntu). This suggests to me that my attempt to get my drivers into their most recent versions on my work PC is actually what broke the tablet.
What do I need to do so that my tablet is recognized by my Ubuntu PC when it is in PC mode?
Original question text:
My new Wacom Intuos S connects to my Ubuntu laptop, and responds to input, but only its left half (or really, left third) works properly. In the image below I have marked the area that works properly.
If I move my stylus outside the rectangular area, my cursor still responds to vertical movement (i.e. moving my stylus still causes my cursor to go up and down) but no longer to horizontal movement (i.e. moving my stylus does not cause my cursor to move left to right).
Listing my devices with xsetwacom lists only my stylus and eraser -- this is inconsistent with an example I found elsewhere, which lists also a cursor and a pad -- but I am not sure if that relates to the problem.
mees@mees-ThinkPad-L480:~$ xsetwacom --list devices
Wacom Co.,Ltd. Intuos S stylus id: 9 type: STYLUS
Wacom Co.,Ltd. Intuos S eraser id: 16 type: ERASER
Running libwacom-list-local-devices seems to give a relevant hint to the problem:
[Device]
Name=Wacom Intuos S (Android Mode)
DeviceMatch=usb:2d1f:0374;
Class=Bamboo
Width=2
Height=4
IntegratedIn=
Layout=intuos-s-p3.svg
Styli=0;
[full output omitted, can report if necessary]
The reported height and width seem to match the aspect ratio of the part of the device I am actually able to use. I can find the config file (?) that lists the information above, and simply edit the width field to have a different value (e.g. 5), but that does not actually change anything except the output of libwacom-list-local-devices (I have changed it back to the default value of 2 for now).
This problem seems to be Ubuntu-specific: I have tried the tablet on my boyfriend's Windows laptop, and it works correctly (after installing the relevant drivers). I have also tried it on my personal laptop, which is nearly identical to my work laptop (also a Lenovo Thinkpad with Ubuntu 18.04) and I have the same problems.
What can I do to get my Intuos pad to work properly? Or how can I effectively troubleshoot?
Please let me know if I should provide any further/more detailed information.
I am unable to open the Settings on my installation of Ubuntu 18.04. There are multiple questions on the site already related to this, but the details of their situations seem different.
If I open Settings by searching the Settings application and clicking on it, its name appears on the top of my screen next to a spinning wheel for a few seconds before disappearing (similar to the situation in this question). If I run gnome-control-center directly from the terminal, it hangs for a few seconds before exiting with a timeout message.
mees@mees-ThinkPad-L480:~$ gnome-control-center
Failed to register: Timeout was reached
I can however get the version:
mees@mees-ThinkPad-L480:~$ gnome-control-center --version
gnome-control-center 3.28.2
I have run
sudo apt remove --purge gnome-control-center
sudo apt autoremove
sudo apt install gnome-control-center
(from this answer) successfully, but it does not solve the problem. The suggestion sudo apt-get -f install --reinstall gnome-control-center (this answer) did not help either.
Some of the answers mention nvidia drivers, but I do not have an nvidia graphics card, so this should (?) not be the issue.
I was in the process of trying to update my Wacom drivers (following these instructions) when the problem occurred.
For my work I started using a ThinkPad-L480 a few weeks ago. I immediately removed the pre-installed Windows 10 and replaced it with Ubuntu 18.04.
Apparently randomly, a few times a day, the builtin touchpad will stop responding to movements. Clicking on the touchpad still possible, as is using the buttons immediately above the touchpad. The TrackPoint (red nub on the keyboard) also still works. I have not found a way of fixing this problem, but it has so far always gone away within a few minutes.
Similarly apparently randomly, the laptop's builtin keyboard will lag. Keystrokes will be registered with a delay, or not registered at all. Sometimes the system apparently registers a key as still down even though I've released it. Similarly, this issue appears regularly (maybe once every other hour) and goes away within a few minutes.
Both these problems occur apparently regardless of what I am doing: sometimes when all I have open is a single terminal, and no other processes running. In particular, I have found no way to trigger these problems. These problems started occurring right after I got the laptop (so it should not be anything I have installed myself).
I ask about both problems in a single question, as they both have to do with the builtin input devices of the laptop, and the problems seem to tend to cluster together (if the keyboard starts acting up, I'm less surprised when the touch pad freezes). But that might just be my own confirmation bias.
How can I diagnose and solve this problem?
I have a directory containing a number of subdirectories. Each of these subdirectories contains a subdirectory which all have the same name. I would like to produce a list of all these files on the command line. So, for example, if I have:
dir1/
file1.txt
subdir/
relevant_file1.c
relevant_file2.c
dir2/
file2.txt
subdir/
relevant_file3.txt
relevant_file4.java
dir3/
subdir/
relevant_file5.cpp
irrelevant_subdir/
unimportant_file.txt
dir4/
subdir/
I would like to have the following output:
dir1/subdir/relevant_file1.c
dir1/subdir/relevant_file2.c
dir2/subdir/relevant_file3.txt
dir2/subdir/relevant_file4.java
dir3/subdir/relevant_file5.cpp
I presume this should not be too difficult using find, but I not quite been able to figure it out. It's difficult to search for this problem because it is so specific, and just searching for "find file by matching on its path" doesn't produce anything useful.
Occasionally, I have edited some file and want to move it to a different folder. (Typically: to a Dropbox folder, where I did not want to work to avoid giving the other owners of the folder constant updates.) I do this, for example, with
mv file.pdf ../../../Dropbox/sharedfolder/subdirectory/file.pdf
Afterwards, I often find myself wanting to change directory to the target directory of my previous move operation. I find myself hitting the up arrow, deleting the final file.pdf, holding left, deleting mv file.pdf and replacing it with cd.
Is there a faster, smarter way to do this? Is there a "move file and then change directory to" command, or a shortcut for the last used directory, or something like that?
