Vesa drivers in Debian 10

Hello,

I've just done a fresh install of the latest version of linuxcnc with debian 10 (Debian 10 Buster PREEMPT-RT ISO) and I'm having some problems switching to the vesa drivers. The integrated intel gpu that I have causes some jitter with the intel drivers, with vesa I got good results in debian 9.

I'm following the same instructions as I did last time (with debian 9):
wiki.linuxcnc.org/cgi-bin/wiki.pl?Troubl...g#Using_Vesa_Drivers
But i get the following error when trying to start lightdm in my xorg log:

[ 1073.089] (II) Module vesa: vendor="X.Org Foundation"
[ 1073.089] compiled for 1.20.1, module version = 2.4.0
[ 1073.089] Module class: X.Org Video Driver
[ 1073.089] ABI class: X.Org Video Driver, version 24.0
[ 1073.089] (II) VESA: driver for VESA chipsets: vesa
[ 1073.089] vesa: Ignoring device with a bound kernel driver
[ 1073.089] (EE) Screen 0 deleted because of no matching config section.
[ 1073.090] (II) UnloadModule: "vesa"
[ 1073.090] (EE) Device(s) detected, but none match those in the config file.
[ 1073.090] (EE)
Fatal server error:
[ 1073.090] (EE) no screens found(EE)
[ 1073.090] (EE)

What does it mean that the driver is bound the kernel?
What has changed from 9 to 10 that I get this error?
Switching the driver to intel with the same conf starts the server ok

I'm attaching the full log and xorg.conf files

Thank you in advance

Hi,
i had the same problem following the guide you mentioned.
For me the display manager changed.
On my debian 10 LinuxCNC 2.8 PreemptRT it was lightdm

Replacingwithworked for me
