Title: TC-4.2.1 with vga=786 kernel option
Post by: ibug on February 03, 2012, 10:44:11 PM

in TC-4.2.1 with vga=786 kernel option
 do not start in 640x480x24
 it startx 1024x768 exactly like without vga=786
and xsetup kernel option works ok

The vga=option sets the vesa mode used by console.

You'll need to use the 'Xfbdev' X server from the 'Xfbdev.tcz' extension to make use of any 'vga=...' boot code. If said X server is installed at the time of the 'startx' execution it will replace the default X server (i.e. 'Xvesa') and use the resolution and colour depth you specified via the 'vga=...' boot code. As you found out, the 'vga=...' boot code has no influence on the 'Xvesa' X server.

IMHO using the 'Xfbdev' X server makes only sense if your hardware does not work at all with 'Xvesa'. If OTOH your system is fine with 'Xvesa' but you want it to start with a resolution other than the default (which is 1024x768x32), then you should use a boot code like 'xvesa=640x480x24' instead.

Of course you should first check that 'Xvesa' supports your target resolution, which you could do by running Xvesa -listmodes

For proper Xvesa setup use, from text mode use xsetup or from control panel Xvesa button.

 take time if mistake

I already told you why vga= does not work.
What made you think  xvesa=640x480x**  would work?
