Nouveau driver fails to load, monitor resolutions limited

[edwards2013]

Greetings from a first time Linux installer.

I recently decided to try running an old piece of hardware using Linux, and after research and some testing I settled on xubuntu 12.04.2. The system is a Gateway 486 machine running an nvidia Riva TNT. For the most part, this is actually working well and I am happy with my choices thus far. Now for the issue. The screen resolution is limited to 1024x768 or lower, which although somewhat useable for what I am doing with this machine, is a bit annoying when trying to work with just about any website. The card and monitor (Samsung SyncMaster 204bw) are capable of more, although I would be happy with 1280x1024 if I can get it there.

I first tried installing the nvidia driver 71.86.15 from their website, and that led to all sorts of new issues but no improvement in resolution. Next came a variety of attempts at an xorg.conf file using modelines and setup suggestions that seemed to do more harm than good. I backed out of that, but I couldn't seem to completely clear the nvidia driver's influence, so I reinstalled xubuntu and messed up my Grub setup. I fixed that problem, so I am running again but still at a limited res. I did a lot more research this time and after digging through many posts and logs, I can see in the Xorg.0.log that the nouveau kernel fails to load and the system defaults to vesa. Further digging with modprobe shows errors inserting wmi, mxm_wmi, i2c_algo_bit, drm, drm_kms_helper, ttm, and the Fatal error inserting nouveau. Per the nouveau.freedesktop.org/wiki/troubleshooting information, running ldd indicates:

desktop:~/ sudo ldd /usr/lib/xorg/modules/drivers/nouveau_drv.so
linux-gate.so.1 => (0x0096d000)
libdrm_nouveau.so.1 => /usr/lib/i386-linux-gnu/libdrm_nouveau.so.1 (0x00961000)
libudev.so.0 => /lib/i386-linux-gnu/libudev.so.0 (0x00c50000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x0014d000)
libdrm.so.2 => /usr/lib/i386-linux-gnu/libdrm.so.2 (0x00a05000)
librt.so.1 => /lib/i386-linux-gnu/librt.so.1 (0x0043c000)
/lib/ld-linux.so.2 (0x00ae4000)
libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0x00e69000)

which I believe shows a difference between the libdrm_nouveau.so.1 and libdrm.so.2, although I am not certain if this matters nor can I discern how to correct it as I did not compile the kernel. Additional searches thus far have failed to show the way out of this (or at least in a method that I can understand). I have log files that I can upload if that helps, but figured I would start this way.

My question then is can this ever work on the setup I have (i.e., 1280x1024 resolution), and if so what would be my next steps to get there. I do like the operation of xubuntu, and the education thus far has been quite a mind stretch.

Many thanks in advance.

That computer is WAY TO OLD FOR ANYTHING... if it really is a Intel 80486 in there, you are runing a miracle machine. Thing is, not even the open source driver supports that card anymore, and how much ram do you have?!?! Can't be more than 64MB, which is too low for even Xubuntu!!!


Are you being legit here?

[edwards2013]

Quite legit. The setup is 640 MB of SDRAM, and as I indicated runs well for the most part. I am not trying to do any 3D work or video playback - merely a separate work and browsing machine from my other equipment.

According to nouveau the Riva TNT is still supported, at least in the documentation I have seen and in the Xorg.0.log file:

That's my understanding, too, from reading this...

Sometimes, monitor's horizontal and vertical refresh rates need to specified on xorg.conf file for it to work on max resolution.

HorizSync 30-80
VertRefesh 50-85

Above is an example of what is needed to be added on your Section "Monitor". Find out what yours is and change the value.

[edwards2013]

Thank you for the reply, but I have tried that already to no avail. As a further test this evening, I created a new xorg.conf file in the attempt to force vesa to utilize the 1280x1024 setting. The Xorg log shows it just being ignored and loading the 1024x768 again. I am still trying to find some combination of settings to achieve a higher resolution, and I did more research into a custom install of nouveau in the hope that it will work but the information available is beyond my skill level right now. If I could get a step-by-step of how to make the libdrm versions match it might be helpful, but then again I keep running into dead ends. I'll keep digging and hope a solution appears.

Edwards

PS - sorry, I'm new to this. This reply was to the suggestion regarding the refresh rates.

[VinDSL]

First thing I would do is make sure nouveau isn't blacklisted.

Open a terminal window, and...

cat /etc/modprobe.d/* | egrep 'blacklist nouveau'

This will check all the files in the modprobe.d folder.

Here's the output on my machine...

vindsl@Zuul:~$ cat /etc/modprobe.d/* | egrep 'blacklist nouveau'
blacklist nouveau
blacklist nouveau
vindsl@Zuul:~$

Nouveau is blacklisted in two different places. Nouveau drivers won't work, unless I comment/delete those lines.

Secondly, I wouldn't be running a xorg.conf file. All that will do is jack things up...

[edwards2013]

Thanks for the reply VinDSL. I have checked this, and to be sure I ran it again per your instructions. Nothing comes up using " | egrep 'blacklist nouveau' ". To be sure, I ran the command with just 'blacklist' and got the information in the attached text doc.

I also have a few days of jacked up results due to the xorg.conf file (including a couple of black screen boots due to mistakes in my entries). I'm just testing to try to get anything to work here, and hopefully once I find a good configuration I can get back to a more streamlined setup. Here is the xorg.conf I just ran, although it did nothing:

Section "Device"
Identifier "Card0"
VendorName "NVIDIA Corporation"
Driver "vesa"
BusID "PCI:1:0:0"
Option "ModeValidation" "AllowNonEdidModes"
EndSection

Section "Monitor"
Identifier "Monitor0"
Vendorname "Samsung"
Modelname "SyncMaster 204bw"
HorizSync 30-81
VertRefresh 56-75
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 +hsync +vsync
EndSection

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection

I tried to keep it as simple as possible to avoid making other things worse. It seems that there is no good combination of supported resolutions common to the monitor, the nvidia card, and vesa other than 1024x768, 800x600, and 640x480.

The somewhat good news is that the EDID information is being read by the system as evidenced in the Xorg log (also attached with info from a non xorg.conf boot, but some sections edited to meet upload size limit). The bad is that nouveau seems to load but ends up not doing so, as also evidenced by this modprobe result:

-desktop:~/ sudo modprobe nouveau

FATAL: Error inserting nouveau (/lib/modules/3.2.0-49-generic/kernel/drivers/gpu/drm/mouveau/nouveau.ko): No such device

Also, please reference the ldd results from last night's post.

I understand that I'm pushing some limits with the old equipment, but as I keep reading and researching it seems that the answer is out there but just out of my reach. Other than the resolution, things are working great.

Thanks for reading.

Are you sure you have Riva TNT? Maybe you have Riva 128 which is the last model before Riva TNT? Also, try 16 bit color depth instead of 24? Just throwing some things to think about.

Well, that's the $64k question. I assumed such based on Windows Device Manager and Display Properties indicating it is an nvidia riva tnt nv4, and Everest output this:

But I opened up the case this morning just to be sure. The primary chip has the heat sink glued to it and I do not currently have the stuff to replace that, so I cannot see the information on top. The card itself appears very similar to photos on line when searching for nvidia riva tnt, so I'm reasonably certain that this is the case. I'll drop by Fry's on the way home tonight and get some of the heat sink glue so I can verify the chip information.

I'll also try reducing the color depth.

Thanks for your reply
