Sometime my usb live distro works perfectly and sometimes not.

In this last case i see that, when i run Konsole i get the following alert:

Konsole is unable to open a PTY (pseudo teletype). It is likely that this is due to an incorrect configuration of the PTY devices. Konsole needs to have read/write access to the PTY devices.


I think that was a problem of permission and i try to look into dev folder but i can't cause the system freezes!!!

I try in different mode but i really can't enter in that folder

I repeat, i get this errore only sometimes... and i really don't understand...

How can HELP ME?!?!?!?

Thank all

P.S.:

my laptop works only with "nohotplug" options at startup and with

udevd --daemon
udevtrigger --subsystem-nomatch=pci
