pamatove naroky Xservera

[Matus fantomas Uhlar]

-> :> ked pouzivam SVGA zeria to asi 5 MB; Je to mozne ze Xserver zerie 4x
-> :> tolko RAM ako potrebuje na zobrazovanie ?

-> : A neni to nahodou tak, ze X server potrebuje pamet na ulozeni obsahu
-> : prekrytych oken??

-> Moze a nemusi, defaultovo zrejme ano. Aktualne nastavenie servera vid
-> xdpyinfo a polozky backing store a save under. Flagmi -bs a -su sa da
-> taketo uchovavanie serveru zakazat (man Xserver), nejaka diskusia je aj
-> pri flagu -wm.

-> Dalej si moze okno povedat, ci to od servera vyslovne pozaduje - ak to
-> pozaduje graficka aplikacia, je to OK, pokial terminal, ktory sa vie
-> prekreslit za desatinu sekundy, je to prasacina. Pre konkretne okno sa da
-> aktualne nastavenie bs/su zistit cez xwininfo. Rychly test: explicitne si
-> to neziadal ziadny z programov rxvt, xterm, netscape, xv, gimp, pcb, tgif
-> ...

Diky zase som trosku mudrejsi. Taxom si kukol ten manual a vysledok:

       -bs     disables backing store support on all screens.
       -su     disables save under support on all screens.

       -wm     forces the default backing-store of all windows to
               be  WhenMapped.  This is a backdoor way of getting
               backing-store to apply to all  windows.   Although
               all  mapped  windows  will have backing store, the
               backing store  attribute  value  reported  by  the
               server  for a window will be the last value estab­
               lished by a client.  If it has never been set by a
               client,  the server will report the default value,
               NotUseful.  This behavior is  required  by  the  X
               protocol,  which  allows  the server to exceed the
               client's backing store expectations but  does  not
               provide  a way to tell the client that it is doing
               so.


Je fucked ze problem som vyriesil tym ze som nastavil 16bit farby (ked ten
Xserver pre Mach64 nedokaze 24...) :((((

Teraz... nechapem ani jedno dostatocne... a tiez neviem ci Xserver dokaze
vyuzit volnu pamat gr.karty (cca 1.5MB) na taketo veci...
