hi,
I've got a HP-T5545 that boots correctly (I can reach it through ssh), but login never appear and screen seems to disconnect.
I didn't notice it until now because I usually don't plug it to a screen; so, I can't tell since when it doesn't have login anymore.
integrated graphic card is Via Chrome9 HC3 connected via DVI w/o adapter:
# lspci | grep -i vga
00:01.0 VGA compatible controller: VIA Technologies, Inc. VX800/VX820 Chrome 9 HC3 Integrated Graphics (rev 11)updating linux-firmware, I get this message
WARNING: No module containing the symbol 'drm_privacy_screen_register' found in: 'drivers/platform'is it related ?
here is complete journal: http://0x0.st/8NlI.txt
do you need anything else ?

I usually don't run X on this machine; I can run a lightweight WM, but problems arise with firefox, and other "heavy" programs commonly used.
indeed, blacklisting viafb allow to reach login with a lower resolution.
is there anything I can do ("easily") to get viafb to work again ?
edit: I've tried linux-lts without blacklisting viafb, it doesn't work either.

viafb might be deprecated in the kernel, like all framebuffer things. The viafb driver itself might need fixing.
Maybe you can play with the old vga=ask, vga=<mode> parameter, which allows you to force a certain
VGA mode.

why do they do such a thing?
isn't Linux supposed to have back compatibility? I mean: keeping linux able to run with "old" material?
are they going to deprecate parallel and serial ports drivers too, or is it already done?

This is a long story: framebuffers are there just to do nice splash screens originally. They they were used by framebuffer drivers
in X. Then people found out that just mapping video ram is not enough to talk to a graphic card, especially in 3D-land. The drivers
are still in there, but you have sometimes to fix them (had lately an issue with a sisfb, which had, let's say, weird ideas how to probe
for the size of the video RAM :-) ).
