Multikey autorepetition in linux and x-win
Has decided to write for this purpose - that most to understand - whether is it in linux a defect or and has been conceived
The basic question in that is that if to press 2 keys - why one repeats only?
Will tell I in a spreadsheet I press downwards and to the right - and in general that I expect that the cursor will run on a diagonal - but it прет only in one direction
Why? It is a defect or and should be?
I for myself have found in a kernel and in иксах places that for it answer - they strangely enough are almost identical that in a kernel that in иксах
And the theory is that - if not to concern ps/2 keyboards - that an essence here in what usb the keyboard sends in a computer of purely event of pressing and unpressing keys - and it is 8 byte package - 1 byte a condition of keys of modifiers - 2 byte a reserve - 3-8 bytes codes of the pressed keys
For this reason usb the keyboard theoretically to serve only 6 simultaneous pressing (without modifiers)
here - a car usb the key at all is not engaged in repetition - in system that in a kernel that in x-win - for autorepetition the usual timer answers - which joins by key pressing - and through the necessary intervals adds pressing
But it is made so - that autorepeat only one key
Here and at me the question is a defect or and should be?
If interestingly I have made patch for x-win for real multikey autorepetition
