I have a dual screen setup where the screens have different maximum resolutions so I choose the lower of the two for both screens.
Since last update, everytime I start the computer it messes up the settings and the lower resolution monitor goes blank. I have to mess around with the settings and even though I acknowledge to save the new setting they are gone again next time I start.
Another thing I just noticed is that Shotcut now exits immediately and I can’t use it at all. It’s completely stopping me from doing my work.
Note I tried removing and reinstalling shotcut but it made no difference.
here is the last line of shotcut startup diagnostics, but sadly I have no idea what is causing it.
[Fatal ] <> Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior QSurfaceFormat::DoubleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile)
Is there any way I can reverse the recent update and preferably just disable them. I was perfectly happy with the way it was all working before and now I’m not.
You can make a script with your configuration and add it to statup. This way every time you start your computer it’ll load your config.
Something like this:
xrandr --output HDMI-0 --mode 1920x1080 --primary --output HDMI-1 --mode 1920x1080 --right-of HDMI-0
Just edit the optios the way you see fit and, save the file some like resolution.sh, make it executable with
chmod +x resolution.sh
And add it to the startup
Thanks, I did try that and certainly it is one way round it but searching for answers on my Shotcut I discovered that would be due to out of date graphics drivers.
The manjaro settings manager told me coudn’t update them due to “optional” dependency “cuda” so I boldly did
> sudo pacman -R cuda
then I let it do the automatic driver update and now it seems to be working again and doesn’t need the xrandr script.
I shall come back to confirm if this does solve my problem once I’ve checked a few more things because others may be experiencing similar issue with graphics intensive apps.
So you mean you were in a partial-upgrade state?
Thats otherwise known as broken.
Please make sure to take care of your dependencies and keep yourself up to date.
I don’t think I ever updated the graphics drivers before and not sure if they are part of the update process.
I don’t remember it ever telling me that an update had failed, I could have sworn the last one just said “done” at the time.
I think my real problem was that this didn’t show until I restarted the computer and then tried to run Shotcut.
I see … so your drivers were never configured and/or they were an older series.
(this is all guessing because no system info or similar. In future see this: How to provide good information)
Although I made some progress Shotcut is still crashing. I tried to view filters and it did a Segmentation fault core dump…
… so let me try providing good information this time.
Here is inxi -Fazy, but can’t see anything suspicious here.

so I looked in /var/log to see what was produced today.
pacman.log confirms I removed and then reinstalled shotcut (which completed without giving any errors).
There is a file there called “lightdm” also Xorg.0.log and Xorg.1.log
Something has got corrupted but I have no idea what I’m looking for.
for a few days Shotcut was working fine, then I did another update and immediately back to the same problem:
<> Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior QSurfaceFormat::DoubleBuffer, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile QSurfaceFormat::NoProfile)
Aborted (core dumped)
I just want to get on with my work and don’t fancy learning all about how to post nicely formatted messages. I have enough problems with esoteric technology way beyond me. So the choices I now see, are:
disconnect my “home” drive (that has all my work) then wipe the file system and start from scratch again hoping I will manage to remount my data drive once that’s working
fork out hundreds of dollars for Windows license on my new computer
switch to a different distro of Linux. I heard “mint” is popular but when I did try that some years ago their distro center got hacked and I end up in a very precarious situation… so Ubuntu then?? IDK.
Why can’t what worked yesterday just be the same again today? I was happy with Windows XP and there is nothing in Windows 10 that would make me prefer it other than teh software I want is no longer XP compatible.
all this may be a red herring as all I have to do is restart my computer and it’s working again. I had done a fresh install of Manjaro on a brand new computer… and done the upgrades every time there were some. So I think it’s a software problem, either in Shotcut or the screen driver.
