I can't see any point using 3.5.12, 13+slavek's updates are so much better. If you made some mistake and repeat it, maybe you get the same result! The only problem I ever had installing 3.5.13 was when mirrors were down... however, I don't use "kde-trinity", too bloated for me. > In the meantime, I am going to find out/learn how to make a bootable USB key > from Exegnu Linux. Some usb keys dont have a proper mbr. If you use the script on the live-cd and it won't boot, this usually sorts it: 1. Plug the drive, don't mount it 2. Establish what the device is (/dev/sdx) like this, it should be obvious (substitute sdx for the right one and MAKE SURE to get it right): dmesg | tail -n 6 3. (su) install-mbr /dev/sdx 4, Mount it 4. syslinux -d syslinux I left mbr tools out of the script, it is a root task with horrible consequences if you get it wrong. @ Slavek: Thanks especially for sorting the sudo/su stuff for Debian, it's all working fine (except konsole-su still prompts for sudo password, even if sudo is not used, this is not so major)... as well as all the other updates.
