I solved the problem. I realized that I had updated the PPA from QT5.12 to 5.12.3 to 5.12.6. Doing an "apt remove qt512-meta-full" does not remove the /opt/qt512 folder. So it was just overwriting files when I updated QT. I had to do a ppa purge "sudo ppa-purge -d bionic ppa:beineri/opt-qt-5.12.3-bi...

After entering in export QT_DEBUG_PLUGINS=1 I reran VLC and got this. Well, the part that's the error. Got keys from plugin meta data ("xcb") QFactoryLoader::QFactoryLoader() checking directory path "/usr/bin/platforms" ... Cannot load library /opt/qt512/plugins/platforms/libqxcb.so: (/opt/qt512/plu...

If that issue has anything to do with this thread then you are still sourcing that qt512-env.sh from some place. If its gone from /etc/profile.d than its not from there, and you will have to retrace you steps to see what it is you did. The error changes when I remove the qt512-env.sh, so I don't th...

Simply remove the file from /etc/profile.d again and make sure to reboot or at least logout and back in, then use Karlchen's method to set the required variable specifically for yuzu. I removed the file from /etc/profile.d long ago and Karlchen's method still works for Yuzu but now VLC and Dolphin ...

Here's the error once I removed qt512-env.sh. VLC isn't the only application effected by this it seems. main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This applic...

Just noticed that I can't run VLC anymore and I get this error when I run it in terminal. This QT crap is really pissing me off. Also I put qt512-env.sh in /etc/profile.d/ with no change. At this point I'm OK with putting in that command that @karlchen mentioned, just so long as it doesn't screw wit...

How about this approach? Exec=/usr/bin/env LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/qt512/lib" /opt/qt512/bin/yuzu That worked. I used this because yuzu is located in /usr/local/bin/, so you can just use yuzu. I'd like to try and make it so I don't need all that for running applications I compiled, l...

I'm trying to run yuzu that I compiled but it requires that I use export "LD_LIBRARY_PATH=/opt/qt512/lib/" in terminal before running it to work. So I put "source /opt/qt512/bin/qt512-env.sh" in .bashrc and it works but only for terminal. It doesn't work for .desktop shortcuts where Exec=yuzu would ...

I found a solution. I installed this PPA and that allowed me to compile RPCS3.

https://launchpad.net/~beineri/+archive ... 2.0-bionic

sudo add-apt-repository ppa:beineri/opt-qt-5.12.0-bionic
sudo apt-get update
sudo apt install qt512-meta-minimal

I need helping updating QT 5.9.5 to 5.10, but I've not had luck. I downloaded the installer and it put a ton of files in /opt/Qt5.10.0 but qmake -v shows 5.9.5. I've tried editing /usr/lib/x86_64-linux-gnu/qtchooser/default.conf to this. /opt/Qt5.10.0/5.10.0/gcc_64/bin /opt/Qt5.10.0/5.10.0/gcc_64/li...

So far so good, everything seems fine now.

Thanks roblm, I'll update if this doesn't stick.

Nobody can help?

Step #3 Install Vulkan

Code: Select all

sudo apt-get install mesa-vulkan-drivers

For Vulkan, I would change this slightly:

Code: Select all

sudo apt-get install mesa-vulkan-drivers mesa-vulkan-drivers:i386

I needed the i386 to get a game that was white-listed on Proton to work.

I've made the changes, thanks.

I have a PC hooked up to a HDTV 4k but running at 1080P and I want the screen to stay at 60Hz but it goes back to 30Hz when I either shut off the TV or if I switch inputs on the TV. I can switch it to 60Hz if I run "sudo xrandr -r 60" but it'll go back to 30. Display doesn't give me options to choos...

For sake of clarity, Please explain the difference between the driver sets, and why one would chose the non-pro driver. To be honest, I myself have no idea what the non pro driver is designed for. AMDGPU and Radeon are kinda like driver packages in that they contain many things. Both have RadeonSi ...

This is a guide for those seeking Vulkan support on their Southern Islands or Volcanic Islands graphic cards. Another name is Radeon HD 7000 series and Rx 200 series. Basically the open source drivers by default use Radeon for these graphic cards, which has no RADV for vulkan support. The AMDGPU-PRO...

Nice that it works but maybe you should rename the thread to something like "For AMD users who can't get Minecraft to work on Mint 19".

I fixed it thanks to your suggestion.

If you're getting "OpenGL: ~~ERROR~~ RuntimeException: No OpenGL context found in the current thread' and using open source drivers, you need to create a config file to fix this. I use an AMD graphics card so I made a 20-radeon.conf in /usr/share/X11/xorg.conf.d/ and put this in it. Section "Device"...

Another update, I'm using Cinnamon now and no problems yet. Would only take a few minutes before it'll freeze. I'll update if it happens again.
