After an update of VLC media player, it became unable to add .srt subtitle files. When I run it in the terminal and try to add a subtitle file, it outputs core stream error: cannot pre fill buffer.
I've already tried reinstalling.
I'm running VLC 2.2.0 on Ubuntu 15.04.
After upgrading Ubuntu 13.10 to 14.04, grub failed to load Ubuntu and threw the error symbol 'grub_term_highlight_color' not found. I followed the solution offered in the Bug Report but this failed for me, throwing the error failed to get canonical path of /cow.
Now, I'm trying to install Boot-Repair to fix this problem on a live pen-drive, using these commands.
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && (boot-repair &)
But after adding and updating the repositories, it shows ppa:yannubuntu/boot-repair 404 Not Found error.
W: Failed to fetch http://ppa.launchpad.net/yannubuntu/boot-repair/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found
Is this problem solvable or is there an alternative PPA for Boot-Repair?
How do I move the PostgreSQL temporary file / cache location? I have limited space on my system partition so it keeps throwing me errors like this one:

Hint: Check free disk space.
When I try to maximize Rhythmbox in my laptop screen (Built-in Display), it jumps right back to my secondary screen (BenQ 21").

Is there a workaround for this annoying bug? My monitors both have the same resolution.
I'm looking for (free) Ubuntu YouTube software that can perform two tasks (could be separate software):
What I've found so far:
If this software doesn't exist yet, I'll try to make it myself.
I've just upgraded from 13.04 to 13.10. I've read in some articles that Ubuntu 13.10 is supposed to have the Linux 3.11 kernel. However the output uname -a states that my kernel is still at 3.9:
Linux joren-8570w 3.9.0-030900-generic #201304291257 SMP Mon Apr 29 16:58:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Do I have to upgrade my kernel manually, or should this have happened / will happen in the future with the Ubuntu upgrade?

How do I find a file by filename in a remote connection in FileZilla 3.6.0.2? I couldn't find a built-in search function so I was wondering wether there are any plugins that could do that.
I noticed this when I was watching a video and it started lagging just before until shortly after a download finished. The second time I monitored it using top and the cpu rises above 100%.
My processor isn't a slow one (Intel Core i7-3630QM Quad Core), and the "average" CPU usage of Transmission is 3% - 4%.
I was wondering what the cause of this curiosity is and what I could do about it (besides using another bit-torrent client).
When I tried to install Matlab using the Software Center, it prompted me for the Location of MATLAB installation(s). Since I am trying to install it, I don't know what to do.
I'm looking for a tool similar to Top but for your graphics card instead of your CPU.
I've got a Nvidia K1000M Quadro graphics card but I would prefer something that would work for all (or most) cards.
I'm looking for a tool for Ubuntu 13.04 that can reduce the bitrate of multiple mp3 files. Does anyone happen to know such a tool?
I have enabled the html5 video's in Youtube. Whenever I play a video in html5, I get to see weird horizantal lines:
I'm using the latest Google Chrome on Ubuntu 13.04. I've got a Nvidia K1000M graphics card with the latest proprietary drivers installed. How do I fix this issue?
When I disconnect my monitor from my laptop, Ubuntu still seems to think that it is plugged in and does't update the display. This issue is Ubuntu specific (not occuring in windows) and my monitor worked fine with another laptop (Ubuntu 13.04, exact same drivers).
system settingsDisplaysI would like Ubuntu to update the display settings automagically whenever the monitor cable gets disconnected. How would I do that?
When adding a ppa repository using sudo add-apt-repository ppa:..., why should I execute sudo apt-get update?
I am new to Ubuntu and I don't see the purpose of it because there aren't packages installed from the repo. It only takes a lot of time to cycle through my installed packages.

In Windows I've tried this but it also didn't solve my problem.
Setting my SATA mode from RAID to AHCI
This didn't work out either. I had to reset it to RAID to get Windows7 working again
Installing 12.04 instead of 13.04
But the problem keeps persisting
Disabling my SLC mSATA cache module
Windows wouldn't start again and the problem persisted
If anyone could provide me with an answer I would be delighted. Thank you in advance.
Running Flash in Google Chrome drains my CPU massively:
I figured that the cause of this issue would be that hardware acceleration of flash is turned off. When I tried turning it by right clicking a flash application and selecting settings, this window popped up:
No hardware acceleration options can be found.
In Chrome, when I open about:gpu, I get to see this:
How do I turn hardware acceleration on in Flash or is there an alternative way of reducing the CPU usage?

I have been trying to change my login screen wallpaper to one of my own using ubuntu-tweak. The wallpapers are located in Ubuntu's default wallpaper folder and I have given all users read privileges on them.
Now there isn't even a wallpaper left on the login screen.
