Hi,
I'm currently running a headless Fluxbox session with TigerVNC Xvnc server on my HPE Microserver Gen10, which has this for graphics:
| Code: | | 01:00.1 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200eH3 (rev 02) |
I never enabled DRM in my kernel, just the Matrox framebuffer driver, which has been enough to get physical VGA console output and for Xvnc to work.
I've started looking into a possible Wayland-based replacement for the remote desktop setup; right now this looks like being labwc + wayvnc. As far as I can gather, Wayland depends on DRM/KMS, so I thought I was out of luck but I see now that there is a (recent?) DRM driver. However its helptext is a little above my pay-grade:
| Quote: | CONFIG_DRM_MGAG200:
│ This is a KMS driver for Matrox G200 chips. It supports the original
│ MGA G200 desktop chips and the server variants. It requires 0.3.0
│ of the modesetting userspace driver, and a version of mga driver
│ that will fail on KMS enabled devices. |
Wut? It sounds like I need to emerge xf86-video-mga in order ... not to use it. That can't be right, can it?
Would appreciate if someone could clarify what I need exactly on the userspace side. (Note I am not at all interested in physical graphical output beyond the VT console I have already; only in providing the DRM/KMS support that Wayland supposedly needs.)
Also I have a worry that these changes might cause some complications with my existing Xvnc setup, which would be bad, so any reassurance that could be offered on that score would also be welcome. |
