Ok.  Please give the output of the following commands, so I can see what packages are installed on each system.

On Ubuntu hd install -

apt list --installed

On dCore -

cat /tmp/.debinstalled

Actually, my old Intel video card does apparently have acceleration.  Installed mesa-utils and below is the output:

Code: [Select]
jason@box:~$ sce-load mesa-utils
* Using nice level 19.
* Integrity and md5sum check mesa-utils.
* Mount /tmp/tcloop/mesa-utils/.
* Update system:
  mesa-utils
* Loaded mesa-utils.sce.

Hi
I see that
Code: [Select]
/lib/modules/4.8.17-tinycore/kernel.tclocal/drivers/gpu/drm/nouveau
is missing

Hi.  Based on your last posts, I also figured that was the difference.  I am compiling a nouveau.ko module now and will upload today for testing.

I have uploaded nouveau-modules-4.8.17-tinycore to the prebuilt repo.  I can modprobe the nouveau module after install, but cannot test it so please sce-import and test.

Hi
tested and the pc freezes during boot after all extensions are loaded, when the screen changes resolution.
Maybe nouveau is not stable yet at least with his kernel

I remember a while back that there was a reason we didn't include the nouveau module, can't remember exactly what it was.  But since you have seen what you are describing and I don't have nvidia hardware to test a build with, I just will remove the nouveau module package.

It was the instability, yes.
The only barriers that can stop you are the ones you create yourself.

Curaga - I now ran across a forum thread where this issue was discussed, and you explained it.  I should have known.  Perhaps Debian/Ubuntu have the resources to make a certain version of the nouveau module work with their kernel version.
