Next zorin 9 lite question, resolution

Elvi

This is a weird one to be honest, first thing first, i was forced to reinstall zorin cause of a goofup making it unable to boot and after i reinstalled everything to what i wanted it... the resolution was stuck to 1024x768x76hz, no chanse to change it at all, this is after i installed fglrx, before it would go up to the lcd's main resolution of 1366x768x60hz BUT the right side of the screen was cutoff by ca 5-10 pixels, not that much but annoying enough :P

On the first install of zorin the pixel cutoff was not there when fglrx was installed and it was on the right resolution but now... any idea's this is driving me mad even if the pc i made was for my dad that don't know squat about computers, it still annoyes me + i can see that the new lcd i bought for him is a litle fuzzy.

Running xrandr only errors out on the first line where the screen should be with this error "xrandr: Failed to get size of gamma for output default"
And the vga line shows it's stuck on 1024x768 resolution.

Oh almost forgot the pc is very old, pentium 4 2.8ghz, 2.5gb ram, 80gb ide drive and a agp ati radeon 9200 series card.
I've scouerd the net for hours to find a solution but not found anything realy that could work + i'm no linux guru far from it but not a total newb either :)

Been a while since I played with lite - when GRUB starts can you get the option to press 'E' or 'Tab' to amend the boot parameters? If you can, add:

xforcevesa - this will force the correct resolution in X - also add 'nomodeset'.

Keep us posted!

Do change at all.

Xrandr just gives this.
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 76.0*

It's like the os can't read the lcd info.

Well i figured as much, but it doesn't explain why with the default drivers the screen get's cut off with a few pixels on the right side of this new 1366x768 lcd, same thing happens when i tried to change the graphics card to a nvidia 5200, yes old too, only one i had to spare, acted exactly the same way and yes i removed the radeon drivers.
I tested zorin 10 lite too... same deal sigh.
Someone suggested opensuse so i tried a live cd and it booted and looked right so uh... yeah *scratches head*

I give up, this seems to be a problem with linux alltogether, there's no issue with that lcd if i plug it into any windows machine i have.
And i was wrong about opensuse and kde that the live dvd ran, it does cut off but not as much but the os looked awfull on that old pc + it wasn't fully translated to swedish my main language, english however translated to russian for some very odd reason o_O.
Anyway going back to 9 lite again as i know it works except for that litle missing pixel bar.

Hi, 10 is only a short-term release anyway (Core is - not sure about Lite) til Jan 2016 so you are better sticking with 9. As for Linux being the issue you have the wrong end of the stick - it is down to proprietary manufacturers of kit failing to provide GNU/Linux drivers. For an awful long time Windows and Intel were colloquially called 'Wintel'! :lol:

Well i think it's the opensource drivers that's failing then cause i've removed the proprietary drivers all together as the drivers that came with the install does give 1366x768 res but with the missing pixels.

I was thinking more on the line of using a mobile/camera and uploading from device/phone. ;-)

Here's the 1024x768 resolution image, i only took of the bottom right corner as it was easiest to see the differance there and i did move the screen so it was towards the left side again just to make it easier.

and the 1366x768 res corner.

It's not like i'm surpriced that this didn't work as it only changes the wallpaper and not the screen.

Also the lcd isn't recoqnised with a name so that could have something to do with it.
What confuses me tho is that this all worked perfectly the first time i installed lite even the fglrx driver worked and didn't go down to 1024x768, it was recognised as a 3d card o_O

This is what i mean when i say it cannot detect the lcd.
Hopefully you can understand it even if it's in swedish :P

I've seen something elsewhere to do with Notebooks to do with 'vendor' somewhere in the command line.

Will get back to you. :D

This is for netbooks so the backlight thing may be irrelevant but worth checking the other commands:

"Open a terminal and edit your Grub configuration file:

Code:
sudo gedit /etc/default/grub


And change the option row GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" as follow:
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux acpi_backlight=vendor splash"

Then update Grub installation with the command:

Code:
sudo update-grub


and restart your netbook"
