Once booted normally, you need to have the 915resolution.tcz extension installed, exit from X completly to a terminal, and issue from there:
Code: [Select]
sudo 915resolution 50 1280 800 32 then
Code: [Select]
startx to come back to X

You might still need to use the kernel option 'xvesa=1280x800x32' at the boot prompt.
To answer your question about this option and where it goes: it must be on the boot prompt. Either typed ***without quotes***   or later added in the 'extlinux.conf' file on the 'append' line, inside the section you're using to start TC. ( 'append' line comes after 'linux/kernel' and 'initrd' lines).

You might need it so that it will be added to the '.xsession' file automatically when TC configures itself at boot.
An important note so, maybe you need to replace the '32' by '24' or '16' eventually, in case your screen cannot handle 32 bits depth.

Hope it works.

I had to reinstall TC in the same laptop and having difficulty with getting the 1280x800 resolution,  Before when was working correctly I didn't need to setup .xsession file.  My extlinux.conf file is below, this doesn't work (doesn't retain the resolution), although on exit to command line and 915resolution 50 1280 800 24 followed by startx DOES with display correct resolution.  After backup and reboot the 1280x800 resolution is lost.  Does the extlinux.conf file look OK?

Code: [Select]
DEFAULT core
LABEL core
KERNEL /tce/boot/vmlinuz
INITRD /tce/boot/core.gz
APPEND quiet  waitusb=5:UUID="87e6221f-fa25-47c6-a98d-18c7c051b2c9" tce=UUID="87e6221f-fa25-47c6-a98d-18c7c051b2c9" xvesa=1280x800x24

Hi puppybyte!
Try adding this to your  /opt/bootsync.sh  file before the line that calls  bootlocal.sh:
Code: [Select]
915resolution 50 1280 800 24Then run a backup. Reboot and see if it comes up in the right resolution now.

thanks!, works perfectly, I should've known to add it to that file by now...
