black screen after startx?
Hi,
Without wasting much time will Come straight to the point,i installed backtrack4(ubuntu based) few hours ago and i am facing a problem in getting into the graphical mode(live cd)!,hence i tryed to check and run it in a "safe graphical mode" and unexpectedly it works fine! but when i switch to 1024x768 resoultion in the same live cd ,and then when i type startx it just produces a black screen! after doing some research on finding a soultion to this problem i found out that this goto do some thing with editing the xorg.conf file! but when i type xorgconfig,it shows an error saying command not found! sudo dpkg-reconfigure xserver-xorg command just talks about the keyboard bla bla bla! nuthin intresting on graphics or screen section! resource: intel corporation 828456/gl 128 mb a kind request towards you,if u have "any" info on this prob or how to modify the xorgconfig file,kindly please reply Regards, Manish87 |

vi /etc/X11/xorg.conf its prolly in the same spot |
Safe graphical mode uses the vesa driver. There is no xorgconfig command. /etc/X11/xorg.conf may not be present by default. - You can create an X configuration file with the following command (as root, from a terminal window):
Code:
Xorg -configure :1 Code:
Xorg -config xorg.conf.new :1 |
One of the best ways: boot the pc with the live cd - copy the xorg.conf from the live cd to the hdd and then reboot and move the saved file to /etc/xorg.config.
Hope this helps. |
Hi,

I think you should follow what rock is saying; cp /dev/cdrom/etc/X11/xorg.conf /dev/sda1???/etc/X11/xorg.conf SDA is what ever partition you installed Backtrack on. and /Dev/CDROM is the location of the Live CD So copy the file from the LIVE CD ----> to your Hard Drive you installed Backtrack on "/dev/SDA1-15" 1-15 represents your partions |
Another thought (for what it's worth - remember, this advice is free). Boot from the live cd and take a look at the configuration file (isolinux.cfg ?) on the live cd. Note the parameters on the kernel line that are used when booting into safe mode. Then just modify your /boot/grub/grub.cfg file appropriately, and boot from the hard drive. Once booted, do a proper modification (by modifying /etc/default/grub - I believe there's a tool for doing this).

When you did that are you logged on as your fresh install? or are you logged on with the Live disc...?
I would boot up the live disc, and once you are in X on the live disc I would mkdir /mnt/whatever mount /dev/hdc1 /mnt/whatever then copy cp /etc/X11/xorg.conf /mnt/whatever/etc/X11/xorg.conf.new once the file is placed in your /dev/hdc1/etc/X11/ DIR i would reboot your live disc X session, and then remove the disc, and boot up your local HD - then i would rename the original xorg mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old then i would rename the .new file we copied over, to the original file - xorg.conf mv /etc/X11/xorg.conf.new /etc/X11/xorg.conf then startx and see if that works |
