I'm trying to put to work the nouveau driver on
slackware 64 bits current, kernel 4.4.*.
I've thought the hardware to be some obscure OEM
variant of GT610. However, kind soul on IRC
pointed out that it's a G98 really, 'GeForce
9300 GS or 8400 GS'.
Proprietary NVIDIA drivers:
* 340.96 installs okay, console works, but X
doesn't start, with unspecified error occuring
when trying to initialise hardware (-19);
* 304.131 works, with no undue surprises.
I've experienced a lot of problems with nouveau
driver (as packaged for Slackware on Dec 16,
2015; build date in logs: '19 November 2015
12:46:02AM'):
1) Console does not initialise the output
correctly if video mode is not restricted to
640x480 by kernel command line with '...
video=640x480'. Any other (bigger) resolution
there, or no restriction, and the screen blanks;
also, for either 800x600 or 1024x768 upper
limits the monitor outputs the warning about
unusable mode, 26.8KHz/43Hz for 800x600, and
21.6KHz/27Hz for 1024x768.
The input works. I can log in and start X, which
starts (!) and works, but produces no output either.
No such problem with NVIDIA drivers.
2) The working mode restriction 640x480 gives
the console set to 68Hz vertical refresh (as
monitor reports).
3) The X started from console (having 640x480
restriction) allows only 640x480 mode in config.
Any other mode produces working X with blank
screen, excepting console started restrictred to
800x600 or 1024x768, which retains the monitor's
floating message about 'unusable mode'. Either
way, input in X works.
4) The X in 640x480 has actual vertical refresh
of 68Hz, which xrandr reports as 75Hz. Attempt
to change vert. refresh rate to 60Hz produces
screen 'stroboscoping'. Any other resolution set
via xrandr produces blank screen.
Any advice? NVIDIA driver files removed, full
dmesg and xorg available. Cut of dmesg with
nouveau lines is in postscriptum.
