Hello again. Seems that the mounting exist without doing anything by me. If I click icon from ED image and it starts even after reboot. Now all generally is working. Just I have met one problem - when wifi is on (in my case) and I start LXDE the left and up-left part of the screen (with taskbars etc.) flickers and I can not do anything. Tried to search the tread with "LXDE+flickers" and similar words, but found things not explaining my problem and it's solution. Have anyone met the same problem?
Otherwise it is very good thing, but unfortunately it did not make what I wanted. Iceweasel was able to install the bank certificates. Establishes the https connection. Since here all fine. But when I decide to sign a transaction the bank site opens second windo to choose the certificate to sign and to enter the master pass of the browser. And here is the problem. The second window is with fixed dimensions which are out of the LXDE dimensions. Then I can't see if the cursor is on the place to enter the master pass and then to push the button "OK" at the bottom of this screen. If there is a way to zoom the whole LXDE probably it will work. I tried ctrl+- but it does not work on this second window. On the main it is working.
Have a nice day
