unable to save screen resolution in KDE

[nfz300zx]

Hi Guys,

I have installed BT5r3 on my laptop, installed bumblebee etc and am really happy with the setup so far, however I have an issue with the resolution in KDE. it keeps reverting to 1368 x 768 after a reboot. I keep setting it to 1366 x 768 (Max res of my screen) and all is fine till I reboot. is there anywhere I can manually set this. I tried looking for the xorg.conf file but that didnt help.

Thanks in advance!

HDD dual install?..USB live? DVD Live?..Video card info being used?

Certainly you could by modifiying a file if HDD install...But need more info..

Luck.

Gfx card is a Nvdia GT640m with intel 4000 intergrated. Screen res should be 1366x768 and the option is in kde to set this but when i reboot it is lost. have installed the bumblebee package as the guides show but not had any luck with the kde res.

You have dual video card...You need to set the default video card, whether it's intel or nvidia. Once set priority, reboot and see what happens.
if you decide to use Nvidia, I would recommend to use the propietary driver. But You need to know what video card is the default and being used when booting.


How to know: open up a terminal and type: lspci | grep -i vga (see the pci-id at the beginning of line in format xx:xx.x)
lspci -vvs xx:xx.x (see at the end of all info: Driver used by Kernel: xxxxxx)
now you know the driver used.

If using nvidia you might want to try using the propietary driver:

Here is the the propietary driver to your card (64-bit): http://www.nvidia.com/object/linux-d...60-driver.html
(32-bit): http://www.nvidia.com/object/linux-d...60-driver.html
Install the linux headers and build-essential before installing the driver.
Install driver.
