[closed]No screen

Eperbab · posted: 2014-05-13 20:16

I tried to update my graphics driver with smxi. Now I don't have a GUI. I had to boot up my fallback OS (Ubuntu 12.04) to come here.
Symptoms: Screen 0 deleted. Same failure with fallback user, root, and X -configure. Fluxbox also fails to start.
interesting part from Xorg.0.log:

Code: Select all

Back up the old xorg.conf and run sgfxi again. Ubuntu should be able to rename the file.
Boot into run level 3 on grub menu for antix sgfxi.

Edit: did you update the kernel?

With recent versions of X-org, you should be able to start the server without an xorg.conf. You could try copying /etc/X11/xorg.conf to /etc/X11/xorg.conf.save and see if you can start X.

It looks like installing the new driver created a conflict with your existing xorg.conf file:

Xorg.0.log wrote:UnloadModule:"radeon"

xorg.conf wrote: Driver"ati"

You could also try editing your xorg.conf and replace"ati" with"radeon".

- Yes, I have mounted AntiX root in Ubuntu to see my files.
- I need xorg.conf, because my TV-monitor has a broken implementation of EDID services. Without xorg.conf, I would have 640x480 43 Hz interlaced mode or something even more weird on a full HD display.
- I have run smxi /sgfxi with various kernels from tty2, including 3.5.0-antix.2-486-smp. I have used the 3.14-1-rt-686-pae kernel for a few days. I have rebooted several times with that kerner without issues before graphics driver update.
- {Driver"ati" ->"radeon"} This is the fastest & easiest attempt to fix it, going to try it first. Strange, that it worked for two years.

Update:
- changing driver name to"radeon" doesn't help
- Boot into run level 3 on grub menu for antix sgfxi: I have used smxi, doesn't help

- removing xorg.conf: half way success. Now I have screen with"1024x768 0 Hz". Last time I had 320x240, or 640x480 without xorg.conf. This time 1024x768. As Neo would say:"Hm. Updates."
Glxgears animation is running. Now I need to build a new xorg.conf to get back 1360x768 16 bit.
I will try again X -configure. Thanks.
Any idea what is wrong with the above xorg.conf after adding the ati -> radeon change?

Two ideas. First, you can use the /usr/sbin/buildxconfig to create a minimal xorg.conf in your current directory:

Code: Select all

CMDLINE=xres=1360x768 /usr/sbin/buildxconfig

Examine the xorg.conf file it created and try copying it to the /etc/X11/ directory. You can also use xdrv to try to force which driver is used:

Code: Select all

CMDLINE="xres=1360x768 xdrvr=radeon" /usr/sbin/buildxconfig

Next, since X is using the frame buffer, you could try booting with a higher frame buffer resolution. Try using the boot parameter"vga=795" to get a 1280x1024 resolutions on the virtual consoles. This resolution often carries over to X with no further effort. I've been able to get 1600x1200 resolution with this trick (using vga=839, YMMV because many of these codes are not standardized).

Use"vga=ask" (and then press <enter> when requested) to get a list of all vga modes available on your machine. It will then give you a choice to pick one. Write down the resolution you picked. It will be in hex. For example the 1280x1024x24 resolution I suggested above is"31B" in hex. So you either need to convert it to decimal (795) or enter it as"vga=0x31b". The size 1360x768 is not standard so there may not be a vga= code for it. You can find out using"vga=ask".

- This one doesn't generate xorg.conf anywhere i have checked: (including /home/user)

Code: Select all

CMDLINE=xres=1360x768 /usr/sbin/buildxconfig

- It generated xorg.conf in etc with sudo (only when there was no xorg.conf), but this configuration failed. Also tried it with the xdrv switch and 1024x768, but X failed. Also failed after some modifications. Strange, but with xdrv=radeon it added a section for nvidia tweaks and I have seen a second monitor (Monitor1) as well.

- Resolution transferred to X (640x480 when entering from init 3 boot, 1024x768 with vga=791).
The vga=ask options displays values for 1280x1024, but anything above vga=792 gives an OSD warning about"invalid format". BTW, at the top of the screen there is a warning about EDID scan turned off. (Thanks, LG, for the broken implementation. Next time I will by a Samsung TV.)
At vga=792 I have seen strange colors, duplicated ghost icons shifted to the left of the screen, so it was unusable. 1360x768 didn't appear even after scan for more options.

- X -configure as root from tty1 fails with segfault at adress 0x00 / 0x11. xorg.conf is generated, but fails with no screen found. After adding a vesa driver X starts, and shows a blank screen without error message.

Anyhow, I have ordered my new desktop (planned aquisition since 2008), so I leave it like it is at 1024x768, and we will see what happens when I move the HDD to the new PC. I will keep this 32 bit installation with a pae kernel as a fallback option. Next task is to install 64 bit Antix-base from usb to SSD.

New stuff arrived. Now I have free way up to 1920x1080 32 bit. I will post the new problems with the new pc in a separate topic.
