X does not start: /dev/fb0: No such file or directory

#1 Post by tomlan »

Hi!
I installed a few week ago Debian Lenny. Then I upgraded to Debian Sqeeze and all worked fine but after few days X failed to start with the error:

Code: Select all

(EE) open dev/fb0: No such file or directory
/usr/bin/X symbol lookup error: /usr/bin/X: undefined symbol: pixman_tramsform_init_identity
I couldnt fix it so i reinstalled the system but this time directly Debian Sqeeze.
This time too, all worked fine 2 or 3 weeks. After the last routine update X wont start anymore with the same error: dev/fb0: No such file or directory
I tried this solution: http://www.linuxquestions.org/questions ... ry-359219/ and added this "vesafb:mtrr,ywrap vga=0x318" in the file /boot/grub/menu.lst to the line kernel:

Code: Select all

kernel /vmlinuz-2.6.30-2-686 root=/dev/sda6 ro quiet vesafb:mtrr,ywrap vga=0x318
Now X does not claim anymore about /dev/fb0 but wont to start anyway. In the log file there are not errors.
The only warning are:

Code: Select all

...
(--) NV: found NVIDIA GeForce 8400 GS at 01@00:00:0
(WW) Falling back to old probe method for vesa
(WW) ) Falling back to old probe method for fbdev
(II) Loading sub module "fbdevhw"
....
The file xorg.conf is not there.
Video device is NVIDIA GeForce 8400 GS.

Thanks for your help!

Install the nvidia driver

Raspberry PI 400 Distro: Raspberry Pi OS Base: Debian Sid Kernel: 5.15.69-v8+ aarch64 DE: MATE Ram 4GB

thanks for your replay.
I tried to install the nvidia drivers, but for my kernel (2.6.30.2.686) there is not a pre build package and both build methodes described in the document you linked failed (m-a auto-install and debian/rules binary_modules).

So I installed the official nvidia driver 190.53. Its right for my video card? (GeForce 8400 GS).
X starts but hangs by the login window. Schould I try another version?

You ought post that Xorg.0.log to be perused.
The file xorg.conf is not there. ??? There isn't one??
Need to post that too. If your relying on using the nvidia driver, then you don't need the famebuffer device.
Whether these are made is determined in the kernel config,

Device Drivers --->
Graphics support --->
<*> Support for frame buffer devices --->
< > nVidia Framebuffer Support │ │ options for nvidia frame buffer devices.
│ │ < > nVidia Riva support

You can select [*] VESA VGA graphics support

to get the vesa driver as ab alternative. You kind of need an xorg.conf to set your driver coice.
X starts but hangs by the login window.
Need that log. Do you get the nvidia spash screen appear? Need to see what's loading.
If the driver is ok, then could be xorg server issue.

Do you get the nvidia spash screen appear? Need to see what's loading.
If the driver is ok, then could be xorg server issue.
yes, the splash sreen appears
Whether these are made is determined in the kernel config,

Device Drivers --->
Graphics support --->
<*> Support for frame buffer devices --->
< > nVidia Framebuffer Support │ │ options for nvidia frame buffer devices.
│ │ < > nVidia Riva support

You can select [*] VESA VGA graphics support
where can I make this onfigurations?


thanks a lot! tomlan

>>where can I make this onfigurations?<<<

You make those configurations when configuring a kernel before building it...not a task that I'd undertake lightly. Anyway, I think the kernel already has that enabled. You could search the kernel config file in /boot to see if you can find that setting. I think the nvidia driver is failing, then the system is trying to fallback on vesa and framebuffer drivers, to no avail.

You could try the sgfxi (part of the smxi scripts (http://smxi.org/) to autodetect your card and install the correct driver for it from the command line...
