[SOLVED] Netboot display cheatcode won't take

[combo3]

I'm netbooting TC2.2 on a Dell OptiPlex GX1 with a maximum display resolution of 800x600x24.

/netboot/pxelinux.cfg/default

Code: [Select]

DEFAULT tinycore
TIMEOUT 300    
          
LABEL tinycore
KERNEL bzImage
APPEND quiet noswap vga=789 initrd=tinycore.gz
Screen size is fine during the boot phase, but reverts to high resolution once the system enters runlevel 5, forcing me to do a Ctrl-Alt-Bksp-xsetup-startx dance.

{Note: I've tried every option under the 640x480 and 800x600 columns listed in http://tinycorelinux.com/faq.html#bootcodes - to no avail. Adding "xsetup" to the APPEND line works, but sort of defeats the purpose of having a "vga=7xx" option.)


Right after booting ~/.xsession shows:

Code: [Select]

Xvesa -br -screen 1024x768x32 -shadow -mouse /dev/input/mice,5 -nolisten tcp -I 2>&1 > /dev/null & waitforX
A remaster with /etc/skel/.xsession changed to 800x600x24 works, but I was hoping for a more elegant solution.

Am I missing something obvious?

After running xsetup.sh and startx, run the backup utility.
The settings will be reloaded next time you boot.

The vga options are for the console. Xvesa and console resolutions are not isomorphic.
As stated performing a backup presists your Xvesa resolution,

Thanks for the replies.

To clarify:

This machine has no hard drive, so I planned on using it as a diskless internet kiosk in a public waiting area -- the kind of place where quick reboots and lack of persistency are highly desirable.


Anyways, I solved my problem by switching monitors. Seems the issue was hardware related.
