When I try to to boot erebos live (xfce, kde-lite and unofficial seminarix-prebuild) X don't don't start correctly.

the kde flavours just show a black screen after entering runlevel 5. On the xfce-flavour, I get following message:

< Yes > < No>


If I choose yes, this output is shown:

Videocard       VIA , VT8378 [S3 UniChrome] Integrated Video  X.Org 1.4.2  [ 1024x768@75.0hz ]

This is the first time some behaviour like this happened on this machine, all previous release (chaos - erebos pre1) worked flawlessly

I tried out some cheatcode (e.g. xmodule=vesa, some different resolutions..) but without success.

md5sums are correct, same behaviour with both cd and fromiso.

Thanks for your report, it seems I made a bad decision for the case when no xserver module was detected for your card, and xorg.conf was generated in such a way that the vesa module is used as a fallback, but it expects Modes to be set manually. I could have sworn that it would use a default set of modes in the recent past...


Please run the following sed hack on the live-cd, after the failure to lauch X. It will add a Modes value to the screen section and confirm the bug if xserver works after it.

Code:

sed -i '/^\s\+Depth/ a\\t\tModes\t"1024x768" "800x600"' /etc/X11/xorg.conf
init 3
init 5

Thanks kelmo for your hint, unfortunately this didn't work. Error messages are exactly the same.
new xorg.conf:

I have found out that saying yes in many tests would cause the system to be non-bootable, the easiest fix I have found is to boot into live cd and copy the xorg.conf to your installed sidux partition and try again. (if using *tainted* drivers you can use smxi -kiwdt and choose option #1, this will remove all binary drivers and from there you can continue to either use the *free* drivers or install the latest binary) Good luck.

Since you are using

VIA Technologies, Inc. VT8378 [S3 UniChrome] Integrated Video

I think your best bet is to just boot to live and copy over the xorg.conf and try again, the above was posted for others using nv or ati

Hi Piper,

this problem appears with the Live-CD.

My fully upgraded Install works without any problem, so i assume the problem has something to do with the live-boot-detection.
btw i have already tried to do the opposite way of your suggestion: to copy the xorg.conf from my hdinstall to the live file system. But no success, x compains unknown module via.

I have also the problem.
Always a gpm mouse error and no X at both XFCE and KDE light, but a working installed system.
I have a AGP 7800GS Nvidia btw

Hi BlueShadow, my mistake for not reading correctly, I thought this was happening on a hd installed system Embarassed

My system will not start either. It looks like it is going to start KDE and then flashes for a second and then goes back to the $ prompt. I have tried both the kde light and kde full versions and get the same thing on both. I am able to install kubuntu, ubuntu, and madriva as well as others with out issues. I know they are not the same but I just wanted to point out that others work on my system just fine.

jmdennis, one or two video cards in your system? Can you show this output:

lspci -nn | grep VGA

I only have one video card and it is the one on the motherboard. Below is the information requested.

jmdennis@jmdennis-desktop:~$ lspci -nn | grep VGA
01:00.0 VGA compatible controller [0300]: VIA Technologies, Inc. S3 Unichrome Pro VGA Adapter [1106:3108] (rev 01)

Have you tried the vesa switch at the grub prompt? ie: replace the vga=xxx with vesa and hit enter.

I tried this but it did not work for me. I do not know why the disc will not even get me to the desktop. I know that some other versions that I tried early on did the same thing but not for a very long time.

I have had this problem with several of the past du's. The solution I have found is to log in as root and run smxi. Go to graphic card installation options. I am using a Nvidia Gforce 5200 card so I select new nvidia driver. Then startx and all works fine.

I have found it necessary to reinstall my video card on several occasions.
