LCD for linux
 

I would say I am a vary causous man , so when I have a chance to have upgrades to my monitor, I just have to do a search for ways to look out installing LCDs

I origionally have a CRT 15' now I got a Benq fp557s-T 15'
This might sound a bit stupid but here it goes.
Is there anyone had replace CRT with LCD b4 ??

I am just wondering if linux is plug and play or we need to config XFree86 first ""b4"" we install the hardware so that the LCD don't get dammage.

Any tips are welcome d:)
maybe i can solve u some of the problem u might have <--- got a old p100 and run into trouble <-- so I might come to the same problem that u might encounter d;)

spec:
dual boot win98se , mandrake 9.1
voodoo 3
C-media 8738
diamondview 15'
PIII 450

I would configure first howeve ron mine I did find that it was just play and pray

Rus

by config u mean refresh rate, (vertical ,horizon) only right ? or get in mandrake in safe mode and use drakconfig to config the LCD

Just change horizsync and vertrefresh information in the XF86Config file in /etc/X11/. You should be able to find out the maximum for these from the info that comes with your monitor. Vertrefresh is generally a lot slower on LCD then crt.


Here is mine

"Monitor"
Identifier "LCD"
VendorName "Hitachi"
ModelName "Unknown monitor"
DisplaySize 338 270
HorizSync 24.0 - 80.0
VertRefresh 56.0 - 75.0
Option "dpms"
EndSection

And you will want to run the LCD in native resolution which is 1024x768 so have something like this

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "LCD"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

thx for the effort buddy d;) greatly appreciated .... but just one small question :

are those config done while I am still on CRT monitor or do the config after I had install the LCD and boot up the computer with LCD then do the config

what I meant is will either of the process harm the LCD or CRT ? or this is just some unban legend that ppl talk about to scare us =)

do u have some problem with ur computer ? I feel bad for not contribute back while taking up ppl's time to answer my stupid questions d;)
:p

np

ive heard the wrong sync rate can harm the monitor as well, but I think most monitors are fairly tolerant of this. But if you change the value then shutdown and boot up with the new monitor everything should be ok. The X system will ignore any changes you have made until you either log out or reboot.

Sornen what means Option "dpms" ??

I got a LG1710B lcd trought the digital output into a ati Radeon 9100 and when I use it in txt mode all works but when I start X the monitor goes in power savin mode
With the analog output all works well!!

Must I enable or load something particular for the digital output??
TnxAll

my dvi output on a gforce ti4200 seems to work with no problems so it may be an issue with the radeon driver
hmmm not sure what dpms is.

I think it doesn't matter if u had change the syn frequency because I set the wrong one , well actually I set it in reverse instead of 50-70 i set to 70-50 and the X just return me an error and refuse to startx

as to the options dpms or dmps ....

it was the energy saving option that most recent monitor should already had, in Mandrake that option is in invoked under
section video
instead of monitor as shown by his XFree86-4 config file d;) <-- enjoy

I'v been trying so hard trying to get my DVI port to work. There just isn't any signal coming out of it. It works fine in XP tho. I installed Linux Nvidia driver and still dosn't work.

Did u had to hack a file? I currently own GeForce 3 with IBM LCD.

DVI I/o
 

Finally guys that encounter same problems...
OK I'm in the same case.
I own a dell dimension 8200 with 1702FP. I get a Nvidia GeForce Ti 300 with constructor open source drivers for linux. Since i have installed linux suse 8.2 my D-sub works well doing some tricks in XF86Config
But still my DVI don't works properly, i can read the screen but all is green- it's not my cable cause it worked on windaube-
Do i need to investigate my driver config and plug something
Do someone can help me???
Thanks

I resolved my problem updating the drivers from http://dri.sourceforge.org and now all works!!
I don't know how goes with Nvidia!I got a Ati Radeon!
Probably you need to find some drivers that support DVI

Don't worry about it dude! We were all newbies at one time :) Eventually you will get to the point where you will be able to contribute.

Besides, just by posting a question you are helping. Since, once it's answered others will be able to use it if they run into the same problem.

XF86Config
 

And if the problem comes from vert refresh and horiz synchro specs?
I have read the whole support docmumentation about my dell 1702fp
and i see nowhere the DVI settings
only one list of tech specs the ones that works with analog...
Help

Are you sure that yr monitor has the DVI??I think you know this thing!!
Try to search on the web for yr monitor specifics or on dell site!!
I thinked it was a refresh or syncro with my problem too but at 99% is a driver problem!!
Bye
