Velox cannot be launched

Question

Velox cannot be launched

ErnestNoga opened this issue a year ago · comments

Whenever I try to start velox it shows the following error message:

~ $ swc-launch velox
running on /dev/tty7
failed to set keyboard mode to K_OFF: Operation not permitted

And when I try as root:

~ # swc-launch velox
running on /dev/tty7
ERROR: Could not create WLD DRM renderer
ERROR: Could not initialize DRM

I use KISS Linux and run custom-built modified void linux kernel

Try running under strace -f. You might also want to build wld with ENABLE_DEBUG=1.

I'm on oasislinux with nouveau drivers and have a similar error.
I added -D ENABLE_DEBUG=1 to the cflags in wld's gen.lua.

my kernel config
Before this I ran chown user /dev/tty1 and the same with tty7. I ran the command from tty1.
I Built in my corresponding nvidia firmware into the kernel because I built it without modules support.

I tried swc-launch -t /dev/tty1 velox and it says: running on /dev/tty1 only.
strace
EDIT: my problem is probably not velox related, it is probably because of the nouveau driver. Next step for me would be to build the kernel with nouveau as a module.
EDIT2: Installed kmod and built nouveau as a module: same issue persists

Works after changed video_drivers=intel in oasis config.lua and ran modprobe i915 (I have an optimus setup). This is probably a driver problem, although @ErnestNoga hasn't mentioned if he uses nouveau too.

Ok, I think the issue is that wld was nouveau support, but wld's nouveau driver only supports the particular old nvidia card I have. I've pushed a new commit to fallback to dumb drm support (which works with any drm device) if context creation fails, even if there is a driver for the card's vendor.

Previously, you'd have to set the WLD_DRM_DUMB environment variable to force this.
