Ruby 2.6 nvidia/ati VGA console problems..

[<plh...@ce...>]

Hi,
I have successfully installed Ruby w/2.6 kernel, but still have problem with the primary VGA console. When switching back to console, I get either:

a) crash (reset needed), if the primary AGP VGA X server is started first
b) black screen in VGA mode with blinking cursor, commands work but no way to get any display (even consolechars -d or vga_reset ain't workee)

My setup is:

KT7S5A motherboard, SiS 735 chipset, ACPI an LAPIC on, IRQs via LAPIC
ATI Technologies Inc 3D Rage IIC 215IIC [Mach64 GT IIC] (rev 3a)
nVidia Corporation NV11 [GeForce2 MX/MX 400] (rev b2)
Kernel 2.6.11.1-ruby
Debian Unstable with distribution xserver-xfree86
Nvidia closed-source server with two Screens - the second is TV.

Any ideas? Would framebuffer console work better? Patched X server?

Otherwise the dualleg is working fine, great job everybody. :-)
