Xorg 7.7, Nouveau drivers and resolution in TC10.1

Hello:

My rig running (usually Devuan ASCII) holds two Nvidia Quadro FX 580 video cards in turn which run three monitors in Xinerama mode using the NVidia 340 legacy drivers.

--- Code: ------ snip ---
01:00.0 VGA compatible controller: NVIDIA Corporation G96GL [Quadro FX 580] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation G96GL [Quadro FX 580] (rev a1)
--- snip ---

--- End code ---

When booting TC10.1, I start off with just one monitor mostly because the xorg.conf file which works perfectly well on two other versions of Devuan ASCII will not work as there are no legacy 340 drivers for TC10.1 which is/should not be an issue as I really do not need to use three monitors with TC.

So I use the nouveau driver available in the TC10.1 repository.

This is what loads in onboot.list:

--- Code: ---Xorg-7.7.tcz
graphics-4.19.10-tinycore.tcz
xf86-video-nouveau.tcz

--- End code ---

Everything seems right save for the fact that I cannot get the 1280x1024 resolution I get with the other setups.

This is the output of xrandr:

--- Code: ---tc@box:~$ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 0.00*
800x600 0.00
640x480 0.00
tc@box:~$

--- End code ---

But the Dell monitor I'm using can do 1280x1024 at both 60.00 and 75.00 Hz.

--- Code: ---tc@box:~$ cvt -v 1280 1024 60

tc@box:~$

--- End code ---

tc@box:~$

I have started to put together an xorg.conf file (adapting the working one in Devuan ASCII) to see if I can get the monitor working but to no avail:

I'm attaching my last Xorg.0.log file.

Any ideas?

Thanks in advance,

Hi madmax

Make sure graphics-4.19.10-tinycore.tcz is at the beginning of onboot.lst.

From the log file:

--- Code: ---[ 24.443] (EE) Failed to load module "nv" (module does not exist, 0)
--- End code ---
I think it may be looking for xf86-video-nv.tcz.

Your bootloader options need a couple of corrections:

--- Code: ---BOOT_IMAGE=/boot/vmlinuz waitusb=4 vga=795 tz=-3 acpi_osi=Linux blacklist=mei_me agp=off ipv6.disable=1 enable_mtrr_cleanup pcie_aspm=off nmi_watchdog=0waitusb=5:UUID="0cf4d199-2dc7-44d7-90ed-3e070d73cd93" tce=UUID="0cf4d199-2dc7-44d7-90ed-3e070d73cd93" initrd=/boot/core.gz
--- End code ---
Remove:

--- Code: ---waitusb=4 vga=795
--- End code ---
Add a space to this:

--- Code: ---nmi_watchdog=0waitusb=5:UUID="0cf4d199-2dc7-44d7-90ed-3e070d73cd93"
--- End code ---
so it looks like this:

--- Code: ---nmi_watchdog=0 waitusb=5:UUID="0cf4d199-2dc7-44d7-90ed-3e070d73cd93"
--- End code ---

From the log:

--- Code: ---[ 24.607] (EE) Screen 0 deleted because of no matching config section.
--- End code ---
I think that's due to card 2 being commented out. See if this works any better:

--- Code: ---Section "ServerLayout"
Identifier "layout0"
Screen 0 "ScreenCenter"
# Screen 1 "ScreenCenter" 0 0

Hello Rich:
Sorry for the delay, I was fiddling with xorg.conf ...

--- Quote from: Rich on October 21, 2019, 12:20:47 AM ---Make sure graphics-4.19.10-tinycore.tcz is ...

--- End quote ---
Done

The list's first four files are these:

--- Code: ---graphics-4.19.10-tinycore.tcz
xf86-video-nouveau.tcz
xf86-video-nv.tcz
Xfbdev.tcz
...

--- End code ---

--- Quote from: Rich on October 21, 2019, 12:20:47 AM ---I think it may be looking for xf86-video-nv.tcz.

--- End quote ---
Fixed.
But it made no difference.

--- Quote from: Rich on October 21, 2019, 12:20:47 AM ---Your bootloader options ...

--- End quote ---
Remove:

--- Code: ---waitusb=4 vga=795
--- End code ---
Removed waitusb=4.

With respect to vga=795, it made no difference.
But it's the only way I can get reasonable size fonts in my 19" monitor, so I left it in.

--- Quote from: Rich on October 21, 2019, 12:20:47 AM ---Add a space ...

--- End quote ---
Yes, caught that right after my last post.
Haven't (yet) mastered the use of paint/copy/paste with the mouse in TC.

--- Quote from: Rich on October 21, 2019, 12:20:47 AM ---... due to card 2 being commented out.

--- End quote ---
I tried a few combinations and it got old really fast ... =-/

So I sat a while and thought that if this xorg.conf worked properly in Devuan ASCII it should work in TC. After all, I transplanted it from Mint into PCLinuxOS and then into two Devuan installations without these issues.

Granted, all this using the NVidia proprietary drivers but then that would be the only difference between these two configurations.

So I took the working xorg.conf and made the changes you can see documented:

As you can see, the complaints we saw earlier are not there anymore but problems with the drivers start at [ 24.705], which may (?) rule out an xorg.conf issue.

A search on the web found me this:

https://nouveau.freedesktop.org/wiki/TroubleShooting/#index1h3

--- Quote from: nouveau.freedesktop.org ---Xorg fails to start with "(EE) [drm] failed to open device"

Your DDX does not work with your current kernel and/or libdrm. There are at least three possible reasons for this: the nouveau DRM kernel module is not loaded, a version mismatch between the Nouveau DRM and libdrm, or KMS being disabled.

First check, that lsmod command lists nouveau. If not, do modprobe nouveau to load the nouveau DRM kernel module, and check the kernel log for possible errors.

If the kernel module nouveau is loaded according to lsmod command, but there are no kernel messages about nouveau at all, then most likely Nouveau KMS is disabled. This prevents the driver to work at all. Possible places to disable KMS are:

kernel command line with: nomodeset, drm.modeset=0, nouveau.modeset=0 or similar
modprobe.conf or modprobe.d/ adding the module options drm modeset=0 or nouveau modeset=0
initramfs carrying the above module options

Check and remove all those that you may find, and retry.
---
Inserting nouveau.ko fails

drm.ko needs to be inserted first. Make sure you are inserting the drm.ko that was built at the same time as nouveau.ko. Your kernel might provide another drm.ko which is incompatible.

I am writing this from my TC10.1 installation, starting X without using xorg.conf.

--- Code: ---tc@box:~$ lsmod | grep nouveau

The nouveau module is not loaded, but Xorg.0.log (the actual one) says it was loaded:

--- Code: ---tc@box:~$ cat /var/log/Xorg.0.log | grep nouveau
[ 245.189] (==) Matched nouveau as autoconfigured driver 0
[ 245.189] (II) LoadModule: "nouveau"
[ 245.189] (II) Loading /usr/local/lib/xorg/modules/drivers/nouveau_drv.so
[ 245.189] (II) Module nouveau: vendor="X.Org Foundation"
tc@box:~$

--- End code ---

2.

--- Code: ---tc@box:~$ modprobe nouveau
modprobe: module nouveau not found in modules.dep
tc@box:~$

--- End code ---

This is what a search for nouveau brings up:

--- Code: ---tc@box:~$ slocate nouveau
/mnt/sda1/tce/optional/xf86-video-nouveau.tcz.md5.txt
/mnt/sda1/tce/optional/xf86-video-nouveau.tcz
/usr/local/lib/libdrm_nouveau.so.2.0.0
/usr/local/lib/libdrm_nouveau.so.2
/usr/local/lib/libdrm_nouveau.so
/usr/local/lib/xorg/modules/drivers/nouveau_drv.so
/usr/local/tce.installed/xf86-video-nouveau
tc@box:~$

--- End code ---

3.
drm.ko is present in the system but nouveau.ko is not

--- Code: ---tc@box:~$ slocate drm.ko
/usr/local/lib/modules/4.19.10-tinycore/kernel/drivers/gpu/drm/hisilicon/hibmc/hibmc-drm.ko.gz
/usr/local/lib/modules/4.19.10-tinycore/kernel/drivers/gpu/drm/drm.ko.gz
/usr/local/lib/modules/4.19.10-tinycore/kernel/drivers/gpu/drm/bochs/bochs-drm.ko.gz

--- End code ---

--- Code: ---tc@box:~$ slocate nouveau.ko
tc@box:~$

--- End code ---

This is where I run out of ideas.
Let me know if you need more data.

Thanks in advance,

I neglected to attach Xorg.0.log for the X sessions without the use of xorg.conf.
So here it is.

Do note the same problem:

--- Code: ---[ 24.326] (EE) [drm] Failed to open DRM device for pci:0000:02:00.0: -19
[ 24.452] (EE) [drm] Failed to open DRM device for pci:0000:02:00.0: -19

--- End code ---

It would seem that what is happening is that for whatever reason, nouveau-firmware (nouveau.ko?) is not listed as a dependency for the nouveau driver.

See this thread from last February by a chap running Ubuntu who had an issue similar to mine:
https://ubuntuforums.org/showthread.php?t=2413018

Specifically this post:

Thanks in advance,

Hi madmax
Try changing:

--- Code: ---Driver "nouveau" # was "nvidia"
--- End code ---
to:

--- Code: ---Driver "nv"
--- End code ---

Yes, you have about 30 minutes to edit your post.
