Linux on 19' widescreen
Hello,everyone.
I have been using Slackware Linux for 3 years and loving it.My notebook has been installed with Slackware 11 and connected to a 19' LG widescreen LCD monitor.However,the display is not displayed with correct resolution.It only shows 1024x768 resolution.
My questions are:
1.How can I use the optimal display resolution,which is 1440x900?
2.Is it true that the color depth in Slackware Linux is not as optimal as windows?I can use 32bit color in Windows.
Trial and error:
1.I have used 915resolution and it gave a choice to select 1440x900.However,it is not successful.Also,I did add modeline to the xorg.conf.Same result.
2.I also issued command "xorgsetup" and it successfully detected my Intel 855GM graphic adapter.As a result,it should support a higher resolution.However,1440x900 is not on the list.
3.I found the website of LG to see whether they release a driver for my LG monitor (I did so in Windows XP and works great)in Linux,but they don't release one.
P.S. My case is different than most of the people because I connect my notebook to a widescreen output.They are using widescreen notebook.Maybe it handles differently in the setting.

You might have to add the option "1440x900" to the modes section of your xorg.conf.

Samoth ,thanks for your reply.
Actually,I did add 144x900 to Modes.Maybe you can take a look at my xorg.conf
Quote:
Section "Monitor"
As a result,I can't really figure out what goes wrong.I read a lot of notes,tutorial and other thing.I have no idea,though.

Your modeline in the monitor section is not a normal xorg.conf entry. You should take it out. The ones in the subsection display are the correct ones.

this is not true, 32bit color is a misnomer see ->
wiki_Color_depth
You should ditch your 32bit depth mode.

So your laptop is not widescreen? You should look up and see if your chipset supports widescreen resolutions.
I think what Randux is saying is move your cut your modeline from the monitor section and move it to the display section:
Code:
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1440x900" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync
EndSubSection

What does /var/log/Xorg.0.log have to say? Usually if your modes are getting ignored/modes are incorrect something is put there.

Thanks to all of the flood messages from you guys,I kinda like getting paid customer service for my "un-paid Slackware Linux".I appreciate it.
Randux ,I got it working on Windows XP after I installed the LG's LCD driver.
bioe007 ,thanks for your correction.I did take a look at the wiki and learned a lot.Thanks again.
Samoth ,I think you are right.I also forget to take a look at the log file for any clues to solve my problem.So,here's my xorg log:
Quote:
II) I810(0): BIOS Build: 2965
Randux ,I think you are right here after I read through the log.
P.S. A random search from google,I came across this website
http://www.intel.com/xxxxx/sb/CS-022544.htm
I will try it right now to see if it works.

Randux ,maybe I have jeopardized my notebook by upgrading the BIOS.It hangs after upgrading to 71% and a pink full screen right in front of my eyes!
I am not dare to power off or do anything right now besides calling technical support of DELL.The "so-called" technical support advised me to wait for 4 or 5 hrs to see whether it is successful or not.How hilarious!If it ain't successful,there's no difference you wait for 4 hrs or 40 days!
I have experienced the "great" technical support from DELL before when the technician gave me a lot of wrong information regarding my notebook.So,I will never,ever buy any DELL computer anymore!
Sorry for my anger towards DELL.But you know the frustration of failed upgrading BIOS and get this constructive suggestion from DELL technical support.She told me you have to replace your motherboard if failed upgrading BIOS at last.I kinda like,I nearly was fooled by your colleague last time that the motherboard should be replaced .However,I sort of "resembled" my notebook according to the online manual and get it fixed at last.
I am at a bad mood right now...

It's just too risky to upgrade BIOS because of what you experienced. I hope Dell will get this fixed soon.
If it's their motherboard, you should insist they fix or pay. If not, whoever supplied the BIOS and motherboard is responsible if it doesn't work.

Randux ,hopefully,I can upgrade my BIOS successfully now.
I wouldn't explain the details because it doesn't matter right now.After I upgraded the BIOS,it doesn't do any good to the resolution.However,I did try Fedora Core 6 LiveCD and it can display the resolution higher than 1024x768 like 1280x something like that.
They use version 7.1 of X11.I don't know if it will affect the result.I have read the xorg.conf but I can't find out a big difference.
Randux ,do you think it's a matter of the version of X11?However,I can't find X11 7.1 in Slackware current...

You can copy your xorg.conf that gives you the 1280x to your Slackware system and try it.
My systems are setup how I want now. But before, I tried some live CDs like Kanotix and Slax and anyone that had a screen I liked and I copied the xorg.conf to my Slackware systems to try them
It's a good way to test copies of the config that you know work on your computer. Nowadays if I set up X on some new OS I use the built-in config generation and then I edit by hand. After you do it a few times it will become simple.

ouch... I upgraded the bios on my inspiron8500
once I'll never upgrade a dell bios again...
sorry for your bad luck.
I wonder if you could re-try i915resolution, this time with a modeline in the correct place in xorg.conf?
I have an i945GM and WS laptop and that was how I got it to work, but of course its not an external monitor.
Also I noticed:
Quote:
to the Device section of your XF86Config file.
It seems to me that you should be detecting LFP (ok) and DFP (
not CRT ) ? Does this have something to do with it?
Also you truncated your server layout from the xorg.conf, are you trying a dual headed setup or use this as a single screen?
I think there is some EDID 'off' option for xorg.conf, that could suppress reports from the monitor which may be confusing your VBIOS. ??
Sorry my advice is not so great, I mostly wanted to share my empathy for the dell bios upgrade

Yes, there are a number of "No EDID" options. You can completely turn it off, or you can turn off different aspects. In order to my TV working, I had to tell X to ignore the devices built-in DPI settings.
