I installed lubuntu 18.04.4LTS 64x alternate recently, fresh install, no partitions, etc. installed the lubuntu restricted extras, and vlc.
mkv files on vlc don't play properly, they basically don't play. No warning signs or error messages, they just stay black, or if I jump forward, display frozen images... sound works though.
I tried every single solution I found on the internet, including reinstalling the operating system twice, to make sure I would start fresh and that my actions where not preventing me from further success...
I downloaded extra packages, codecs, allowed and disabled hardware acceleration.
The fun thing is that, when reinstalling mpv by
sudo apt-get install mpv mkv files play way better on it than on vlc, but still play slightly slow, not quite right...
If I go to system profiler and benchmark, I can read
Intel Celeron n2815 1.86GHz
Also, Graphics: 1366x768 (unknown) theX.org foundation
sudo lshw -C video I get the following, that I don't know how to interpret:
*-display description: VGA compatible controller product: Atom Processor Z36xxx/Z37xxx Series Graphics & Display vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 0c width: 32 bits clock: 33MHz capabilities: pm msi vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:92 memory:d0000000-d03fffff memory:c0000000-cfffffff ioport:f080(size=8) memory:c0000-dffff
Any help would be greatly appreciated, figuring out what is failing, if my codecs and drivers are right...
