Intel Desktop Scaling

Control the scaling of the LCD screen to stretch the screen to use full LCD. (LVDS1)


  Setting scaling mode

This can be useful for some full screen applications.

xrandr --output LVDS1 --set PANEL_FITTING param

where param can be

    * center: resolution will be kept exactly as defined, no scaling will be made,
    * full: scale the resolution so it uses the entire screen or
    * full_aspect: scale the resolution to the maximum possible but keep the aspect ratio. 

If it does not work, you can try

xrandr --output LVDS1 --set "scaling mode" param

where param is one of "Full", "Center" or "Full aspect".
alias intel.stretch='xrandr --output LVDS1 --set "scaling mode" Full'
alias intel.center='xrandr --output LVDS1 --set "scaling mode" Center'

Intel Video Crash (Archlinux)

v86d

X

cd /etc/X11/xorg.conf.d/
nano 20-intel.conf
Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
   Option "NoAccel" "True"
EndSection


Framebuffer Fix Intel GMA and IBM T61

pacman -Sv v86d
edit /etc/default/grub commenting the GRUB_GFXPAYLOAD_LINUX=keep

Take quite out too (sucks)

grub-mkconfig -o /boot/grub/grub.cfg
nano /etc/mkinitcpio.conf

Add v86d and i915

MODULES="i915"
HOOKS="base udev v86d autodetect modconf block filesystems keyboard fsck"
mkinitcpio -p linux

Reboot the system (unmount if rescue too)

Optimize Resolution

cat /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes
nano /usr/lib/modprobe.d/uvesafb.conf
# cp /usr/lib/modprobe.d/uvesafb.conf /etc/modprobe.d/uvesafb.conf

and then add an entry in the FILES section of /etc/mkinitcpio.conf pointing to your configuration file, like so:

FILES="/etc/modprobe.d/uvesafb.conf"

I kept the default

Notes

Other

took quiet out of /etc/grub/default too
