Well I would suggest you try harder.
Seriously post your hardware specs, check your md5sum, tell us what guide you followed and what you have tried to do to get it fixed.
Furthermore don't ever make another useless post with so little details. We are not here to guess your problems for you.

My way to fix it:I installed radeonhd drivers.But after reboot x says no screen found.Sorry for my bad english.
Ati radeonhd 4650.Acer aspire 6930G.

I'm not a pro in solving problems but I managed to solve quite a bit resolution and sound related problems in BT4 for myself

So here's what you can do.

Step 1: Check whether Drivers are detected.

lspci -v

Step 2: Check whether X was able to detect those drivers with supported resolution in the log file here

/var/log/Xorg.0.log

Step 3: And then if all goes well above you have to edit this file

/etc/X11/xorg.conf

by following instructions here

Howto: change resolution/refresh rate in Xorg

Hope you can solve further.

I had the problem of flickering due to resolution which I solved in this post

VGA compatible controller: ATI Technologies Inc M96 [Mobility Radeon HD 4650]

Video card detected.
Default screen resolution of my laptop is 1366x768.Is this line of xorg log allows me to set this redolution?

(II) VESA(0): Modeline "1366x768"x0.0   72.33  1366 1414 1446 1526  768 770 775 790 -hsync -vsync (47.4 kHz)

When i type dpkg-reconfigure xserver-xorg and configuered it, xorg.conf becames empty again:

Section "Device"
	Identifier	"Configured Video Device"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
EndSection

I don't know what shall i do.

I also had the same empty xorg.conf file.
Now you have to edit it according to your log file in /var/log/Xorg.0.log as I have done in my case...

You might want to refer to the link I provided before editing.

Also note that I have to bring Monitor section before Device section as it was giving me some error....

here's my xorg.conf file.

Section "Monitor"
        Identifier      "T710BH"
        HorizSync       30-71
        VertRefresh     50-160
# 1024x768 84.89 Hz (CVT 0.79M3) hsync: 68.68 kHz; pclk: 94.50 MHz
Modeline "1024x768_85.00"   94.50  1024 1096 1200 1376  768 771 775 809 -hsync +vsync
EndSection

Section "Device"
        Identifier      "Configured Video Device"
        Driver          "vesa"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "Configured Video Device"
        Monitor         "T710BH"
        DefaultDepth    16
        SubSection "Display"
                Depth 16
                Modes "1024x768_85.00"
        EndSubSection
EndSection

And I had created the modeline using cvt command as follows

cvt 1024 768 85

Good luck for editing....
Though I had made modeline for 1024x768, I can still use 1280x1024 resolution.

The important thing here was HorzSync and VertRefresh which I got from Monitor's manual.


One more thing have you tried fix-vesa command before executing startx ? This might be another solution if it works.

Hi,
I suggest you to verify you ati driver installatiion, it could be a bit messie,
so try to be sure that your driver are running.

Then edit your "/etc/X11/xorg;conf", to reflect the change on x, like MASTERofMINDS say,
moreover you can search on google for specific modifications of the xprg.conf on your model,
I could save you long time,

Hope it can help.
Peace
