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

On Fedora its located right here.. thats the direct file for X11 video, and input devices


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):. This will create the file xorg.conf.new. Edit as needed, test it , and when it's working, copy it to /etc/X11/xorg.conf. Restart your X server (if you don't know how to do that, just reboot).

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,

thanks for the reply zerosignal,rockdoctor and silver black,sry if the questions are lame,but i am still a new bie in linux world! neways

my graphics card model and size

VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE C hipset Integrated Graphics Device (rev 03) (128mb)

horizontal and vertical sync of monitor

30-55 khz
50-120hz


@zero signal: this is the ouput of your command,but i still can't figure it out on how we can edit this file xorg file ,

output:

If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

rock doctor:

i did try the command which u gave me on my terminal! both ended up giving me a "black screen" again! any other alternatives on how to edit xorg.conf?


silver black:


can you be more precise on how to "edit xorgconf" to my respc graphic card n monitor resolutn!



Kind regards,

my way just opens up the xorg.config file;

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).

hi,

thankx for the reply rock,silver and zero.

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

Manish87

I mean, 15in LCD? 19in LCD, 22in LCD Wide Screen?

Oops! apologies for the wrong info!

its 15 inch crt monitor

Are you able to adjust screen size at all from Display Manager inside of X?

i can adjust the screen size to 800x600 and 640x480 but then i get way too huge icons!

the refresh rate is set to 0 and when i click the configure icon just below it i get a blank window!

goto a command prompt and type
lsmod

and post the results in here
