Resize Screen Resolution

Anyone know how I can get the screen resolution to 1,366x768 on my Acer Aspire 751h netbook? I installed Karmic from Wubi, I only get one screen size option and it isn't the one I want.
Thanks

Re: Resize Screen Resolution

Arggg. You were ulucky to get the only Intel IGP that is not supported brilliantly under Linux. You'll find lots of posts on the web about the issue, here is one:

The short of it is, linux support for that chipset is shaky at best, and most likely you are using a very basic VGA generic driver

That explains why you can't change the resolution. You can search for Poulsbo and Karmic and see if there is any progress ...

Re: Resize Screen Resolution

In other words, 'forget Kubuntu on my netbook until this is sorted'??
Are there any other versions of Linux available that would give me a good looking screen? I am not techie and need it to work for me.

Re: Resize Screen Resolution

I wish I could help more, but I don't personally know, Intel really screwed this one up. There may be some pointers in the comments to this story (the Phoronix community is very savvy)

Good luck!

Re: Resize Screen Resolution

I stumbled across a distro called JoliCloud. It's lightweight, built for netbooks and supports the DMA500 chip. It may be a bit blasphemous posting other distros on here but it solved the problem for me. If Kubuntu ever get this resolution, driver thing solved I'll consider switching back but between Windows and any Linux distro on my Acer 751h, I'll go for Linux.

Re: Resize Screen Resolution

1366x768 is notoriously difficult to setup for some reason. I ended up running 1365x768 on one box. I'm going to check out that other one...

Re: Resize Screen Resolution

I got a 1366x736 and mine works. I have an HP and the way I got it to work was going to Hardware Drivers and upgarding your videocard to the option they give you. It will say [Recommended] next to it. And click on Activate. You will need a reboot. Also, if you have nvidia you mind want to do "sudo apt-get install nvidia-settings" . It will help you support multiple monitors for the future

Re: Resize Screen Resolution

I simply cannot get that resolution with my Intel 945gm video card. I'm attached to a 50" plasma TV and would love the correct resolution.

Each driver release from Intel seems to get a little better so I'm not giving up yet.

Re: Resize Screen Resolution

Just in case anyone else has this problem on an Acer 751h netbook (or other DMA 500 chips, maybe) I finally managed to sort mine out. I got this on a Linux Mint forum. Many thanks and all credit to the original poster 'fakrishams'. It worked for me.

it's easy

you must connected to the internet

just open terminal and enter this first code:

sudo apt-get update
sudo apt-get upgrade

after you enter the code it will promp you for your account password and press enter(you can't see your account password but it there)

after the process done, restart

after reboot,

open terminal for one more time

copy this and paste into terminal:

sudo wget http://gma500re.altervista.org/scripts/poulsbo_ppa.sh && sh ./poulsbo_ppa.sh

enter you account password and press enter(you can't see your account password but it there)

after the process done, restart..

There you have it,,, enjoy..

I've test this and its work

Yout linux mint now is fast and your screen resolution is now 1366x768

p/s sorry if my english is not correct becouse I'm still learning..

Re: Resize Screen Resolution

NOTE: This script referred to above was written for Acer AO751h. It does more than just install the video drivers.

If you want to try it on your system, you might consider editing the script beforehand and removing anything not intended for your system.

Here's the script contents:
