using 915resolution : reply to mid

Using 915resolution tool is infact very easy. If you read the README file provided with it, you can use it without any confusion. Anyway, here I will write again, for the sake of completeness, how to use 915resolution.

NOTE: You must be root to install 915resolution.
$ su

#915resolution -l [ list all available Modes ]
Intel 915GM VBIOS Hack : version 0.1

Chipset: 915GM

Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1024×768, 8 bits/pixel
Mode 38 : 1280×1000, 8 bits/pixel
Mode 3a : 1600×1200, 8 bits/pixel
Mode 3c : 1920×1440, 8 bits/pixel
Mode 41 : 640×480, 16 bits/pixel
Mode 43 : 800×600, 16 bits/pixel
Mode 45 : 1024×768, 16 bits/pixel
Mode 49 : 1280×800, 16 bits/pixel
Mode 4b : 1600×1200, 16 bits/pixel
Mode 4d : 1920×1440, 16 bits/pixel
Mode 50 : 640×480, 32 bits/pixel
Mode 52 : 800×600, 32 bits/pixel
Mode 54 : 1024×768, 32 bits/pixel
Mode 58 : 1280×800, 32 bits/pixel
Mode 5a : 1600×1200, 32 bits/pixel
Mode 5c : 1920×1440, 32 bits/pixel
Mode 60 : 1280×770, 8 bits/pixel
Mode 61 : 1280×770, 16 bits/pixel
Mode 62 : 1280×770, 32 bits/pixel
Mode 63 : 512×771, 8 bits/pixel
Mode 64 : 512×771, 16 bits/pixel
Mode 65 : 512×771, 32 bits/pixel

NOTE: please notice that 1280×800 is not listed anywhere in the list of avialbale modes. Schade!!! So now you have to change VBIOS settings to include our darling 1280×800 resolution in it. So we have to rewrite some available mode to 1280×800. I know you will feel like re-writing all of them to 1280×800, I can understand the temptation. Even if you do, nothing will happen, but we isght want to use soem other resolution, at some other point in time and space :)). So take one of them, which you hate, I hate mode 38, so What I did was:

#915resolution 38 1280 800

and that is all. Now check whether it really wrote VBIOS or not, do the following:

#.915resolution -l
Intel 915GM VBIOS Hack : version 0.1

Chipset: 915GM

Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1024×768, 8 bits/pixel
Mode 38 : 1280×800, 8 bits/pixel
Mode 3a : 1600×1200, 8 bits/pixel
Mode 3c : 1920×1440, 8 bits/pixel
Mode 41 : 640×480, 16 bits/pixel
Mode 43 : 800×600, 16 bits/pixel
Mode 45 : 1024×768, 16 bits/pixel
Mode 49 : 1280×800, 16 bits/pixel
Mode 4b : 1600×1200, 16 bits/pixel
Mode 4d : 1920×1440, 16 bits/pixel
Mode 50 : 640×480, 32 bits/pixel
Mode 52 : 800×600, 32 bits/pixel
Mode 54 : 1024×768, 32 bits/pixel
Mode 58 : 1280×800, 32 bits/pixel
Mode 5a : 1600×1200, 32 bits/pixel
Mode 5c : 1920×1440, 32 bits/pixel
Mode 60 : 1280×770, 8 bits/pixel
Mode 61 : 1280×770, 16 bits/pixel
Mode 62 : 1280×770, 32 bits/pixel
Mode 63 : 512×771, 8 bits/pixel
Mode 64 : 512×771, 16 bits/pixel
Mode 65 : 512×771, 32 bits/pixel

and lo, old mode 38 is gone to make way for our own 1280×800 resolution. To check it and see 1280×800 for the first time on your machine, restart the X server. I guess init 3 and init 5 will do. —OR— do Ctrl-Alt-Backspace. I know at this time you will say wow!!!

…..Fireworks….....
…..Fireworks…......

So after having enough firework, you will restart your machine to sadle notice that your 1280×800 is gone and once again 1024×768 will greet you back. This happens because 915resolution thing does not permanantly replace this VBIOS mode settings. To do this insert follwoing lines in your /etc/rc.d/boot.local file:

/usr/sbin/915resolution 38 1280 800

and you will never have to bother about resolution buisness again.

Thanks by your rapid !!! but I dont get 1280×800 resolution. I believe that the problem is in my xorg.conf ….

Could you give me your xorg.conf ? ….

NOTA:

I have tried with mandriva 10.2.

I just want to say thanks for your post. It helped me after 3 days of frustration on my Brand New Dell Laptop. Everything worked under Mandriva, including bluetooth and wireless. The only frustration was the screen resolution. It looks wonderful now! Woo Hoo! Thank you again.

Is there anyway to change the resolution with linux? Just received a new work laptop (Dell Latitude D610) with Mobile Intel 915GM/GMS, 910GML Express Chipset on Windows XP and can't get higher than 1024×768. Very frustrating!!

Thanks in advance!

Sorry, meant to say WITHOUT LINUX!!!

This plain works. Clear instruccions along with 915resolution package. It also saved me after a lot of frustration. I–m running ubuntu (dapper) in a Dell Inspiron 6400 and this works fine for 1280×800 on the first screen and 1280×1024 in the second one.

Initially it also changed the aspect ratio of my 2nd screen but after a reboot thigs were perfect.
Thanks for a good explanation.

Hi, this 915Resolution seems like a great tool, but is there any way to get it to work on Win XP? I have a Panasonic W5 that cannot drive 1440×900 on my external monitor even though the monitor is capable.

You f*ckin ROCK!
Thanx man, got the first time i ever tried it.
Btw, i use Fedora, and the script i used was the /etc/rc.d/rc.local. It’s probably the same thing, but different name due to me using a different distro (if you can’t tell, i’m still a little new to *nix).

Btw, in case anyone needs to know for their own uses, it was a Dell Inspiron E1505

hey im new to linux, i got the res to work, but i cant seem to find the *.local file i need to edit.

Im using Ubuntu Edgy right now.

someone told me it could be the /etc/init.d/bootmisc.sh but i didnt work either.

is there anyone using ubuntu who could tell me?

thanks in advance =)

Thanks for the help. The Ctrl-Alt-Backspace is what I needed. That was not in the readme I saw; it recommended typing startx, which gave me an error.

btw, i dont have any rc.d folder a have from rc0.d to rc6.d and a rcS.d but in none theres a boot.local =S

i only added the followin at the end of my /etc/init.d/bootmisc.sh

---------------------------—-
echo “Usage: $0 start|stop” >&2
exit 3
;;
esac
/usr/sbin/915resolution 54 1280 800 32
: exit 0
---------------------------—-

i have that config cus im on a dell inspiron 6400, widescreen

GOOD LUCK EVERYONE ;)

Hey,
Thanks, it just worked perfect…... though i have not set the auto boot property.

For others
-----—-
I’ve Fedora Core 6 installed.
My resolution is 1280×800
and I’m using Lenovo N100

Hi there, its me again, forgot to tell that…....... to make the resolution automated in startup of Fedora Core 6
open the following file with gedit
root@localhost~>gedit /etc/rc.d/rc.local
and then add the line to the file, that the author said….....
/usr/sbin/915resolution 38 1280 800
so, my file (rc.local) looks like this -
#!/bin/sh #
1. This script will be executed after all the other init scripts.
2. You can put your own initialization stuff in here if you don’t
3. want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/usr/sbin/915resolution 38 1280 800

But, unfortunately i’ll comment this added line, because since i added this automated resolution fix, my sound doesnt work.
so, if anyone has any idea or suggestion, pls let me know !
thanks.

I have a Dell Inspiron E1505 with Intel 945 chipset and I simply can not get this to work. So I changed mode 50 to be 1400×1050 16 bits. Now how (when I startx) does it know to use mode 50? I have fiddled with my xorg.conf with no luck.

I can startX and beleive the modes are changed but when I reboot the system and login as something other than root, the resolution is gone. I have a file called /etc/init.d/915resolution with this line in it:

/usr/sbin/915resolution 50 1400 1050 16

and a link from /etc/rc.d/rc2.d/S90resolution to ../init.d/915resolution

If I init 2 then I see that it gets run. However if I init 5 and login to my account, no resolution. But from the black screen, if I startX , the root account comes up with resolution.

Any ideas?
