Porteus

Hello! I'm running 32bits 3.1.1
When I boot porteus in text mode I've screen size set to
standard : 80x24 (640x480) short
add vga=9 : 100x34 (800x600) better for me in text mode
whatever the pc/screen I use.
Then I startX which uses a screen size very difficult to read
--> but how to reduce this size when X or set another default?
Then I close the X session, and so return to text mode but with
the screen size always setted by startx
--> but how to reduce this size to have again boot vga=9 size
many thanks to avoid rebooting though the boot time has been reduced but the reboot !.

from the description above i'm guessing that you have nVidia card and running opensource nouveau driver - is it?

how to reduce this size when X or set another default?

open terminal and run 'lxrandr' for lxde or 'krandrtray' for KDE which allows you to lower resolution

how to reduce this size to have again boot vga=9 size

when you enter startx then KMS drm driver gets loaded as nouveau requires it - no other way around. KMS is responsible for setting max resolution in both: text and GUI mode.
once you go back to text mode you need to unload KMS manually, have a look here:
http://nouveau.freedesktop.org/wiki/KernelModeSetting
you can do it with a script provided on the site linked above: please modify the script if you have ATI or Intel card.

let us know if that worked for you.

I can change screen size by using lxrandr thanks
krandrtray is inoperative

when I

echo 0 > /sys/class/vtconsole/vtcon1/bind

the system hangs-up
only a hard ipl can restart porteus

the system hangs-up

so you have no other choice than to use Vesa driver for GUI. performance will suffer but you will preserve 800x600 resolution in text mode.
please add 'autoexec=vesa-mode' cheat to your porteus.cfg
