"Dinar, could you try the image from http://people.debian.org/~sthibault/tmp/mini.iso to see whether it helps? "
i have downloaded it but then become afraid , that malware may be there. (even if i remove hdd, firmware can be infected). maybe i will/would do it, when/if i read some amount of information about you. "This bug report is unlikely to be actionable unless you specify *exactly* which model of computer you are using. There are literally hundreds of different touchpad devices out there." i was going to write exact laptop model, but i became afraid that this information can help somebody to infect my laptop's firmwares. and seems that info is not useful to know out exact touchpad model.
