Monitor not properly configured in Heron Beta install, poor LCD display!.

[ElZorro]

Hi,
Thought I would take a look at Kubuntu H.Heron beta----

However it seems impossible to reconfigure a Viewsonic monitor in Hardy beta despite editing xorg.conf
The beta seems to give HorizontalRange 28-33 VerticalRefresh 43-72 for all LCD monitors with no way of changing it.
Viewsonic is HR 30-82 Khz VF 50-85 Hz. and 1400x900 max resolution.
This gives a flickering display with an old 8x AGP 128mb nvidia card NV driver and 800x600@60Hz display-awful.
With an old AGP Radeon ATI on same P4 machine it gives max 1280x800@60Hz, slightly better.
Is there any under the hood way of adjusting 1400x900 screen res in Kubuntu Hardy Heron Beta.
Seems not through xorg.conf
Grateful for any input here.
Cheers and Thanx

I'm using ViewSonic VX2235wm + Ati 9600 XT (fglrx drivers) without problems (1):

Monitor and Screen sections from my xorg.conf:

Section "Monitor"
	Identifier	"VX2235wm"
	Option		"DPMS"
	HorizSync	30-130
	VertRefresh	50-160
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"ATI Technologies Inc RV350 AR [Radeon 9600]"
	Monitor		"VX2235wm"
	DefaultDepth	24
	SubSection "Display"
		Modes		"1680x1050" "1400x1050" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

Have you checked /var/log/Xorg.0.log ? Maybe there is explanation.

Errors:

grep "(EE)" /var/log/Xorg.0.log

Warnings:

grep "(WW)" /var/log/Xorg.0.log

(1) displayconfig (System Settings > Monitor & Display) is making non usable xorg.conf. KDE will start to the text mode. Bulletproof X is (was) not working.

HardyHeron/Beta/Kubuntu

Bulletproof X is a failsafe mode for X that will launch if the /etc/X11/xorg.conf files does not result in a working graphical environment due to Xorg failing to start.

edid problem ?

Bug #194760 in xorg-server (Ubuntu) / EDID fail

Current xorg in Hardy usually autodetects your monitor, it's resolution, dpi, etc. and everything just magically works. This happens because modern monitors can be queried for 'EDID' data, that returns all the necessary info to configure things properly.

However, there are cases where the monitor fails to report EDID...

Hi rog131
your advice worked after a fashion and gave a res of 1400x900, so muchas gracias amigo!
However the monitor HorizontalRange 28-33 VerticalRefresh 43-72 did not change.
So (K)ubuntu must run a generic HR and VR in a very ad hoc manner that cannot be changed.
This monitor configuration shoud be accessible but seems not so, and editing xorg.conf makes not a scrap of difference to these paramaters as though they are set in stone.
Guess this is buried in the xserver somewhere in code in a "hope for the best" way.
Oh well ad hoc sorta works, but seems less than ideal! Perhaps HR and VR are totally arbitrary figures anyway?

Re 'EDID' This Viewsonic 19" VA1912w seems much less of a plug and pray beast, designed as usual for MS with drivers, as Gutsy could not configure it properly either. Feisty however, could do so automagically, and thus got more brownie points.
Linux is usually better with older harware and even backwards compatible so here's hoping.
