[SOLVED] Graphics won't work on fresh Debian install - over range

[mike4ty4]

Hi.

I just did a fresh install of Debian GNU/Linux a computer with an ASUS EAH4350 (ATI Radeon HD 4350 chip) graphics card and the graphics didn't come up -- the monitor said "over range". I can't get you the /var/log/Xorg.0.log as it's too long for one but it mentioned something about using "shadow framebuffer", etc. could that be the problem? Also, the X config file appears to be skeletal. If I generate a new X config file with "X -configure", I get a more filled-out looking config file but it still doesn't work (same monitor problem), and in that config the driver is set to "vesa" and it's listed as "Unknown Card". What's going on here? Is this card unsupported by Debian? Do I need a newer Debian release? (I think this one was like 1 year old or something.) I tried adding settings to reduce refresh rate, etc. but that didn't help either.

Try this Generic Configuration and install ATI Proprietary driver after fixing Graphics Problem.

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

Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
	HorizSync	30-71
	VertRefresh	50-160
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"Configured Video Device"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" 
	EndSubSection
EndSection

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"
	InputDevice	"Generic Keyboard"
	InputDevice	"Generic Mouse"
EndSection

Hmm. It seems just adding the subsection about "Display" specifying modes resolved the problem. I didn't need the rest... Maybe it was just setting the resolution too high for any of the monitors I had (1920x1440 was the highest that appeared in the Xorg.0.log and none of the monitors I have go up that high.).

Refresh Rates also play an important role in Display settings Correct Refresh Rates enable higher resolution.
Anyways, if Display resolution sorted out your problem, no need to play with xorg.conf unless its necessary.
