    Default problemi con scheda video Intel Corporation System Controller Hub (SCH Poulsbo) Graph

    ciao a tutti..ho installato bt4 r2 su un eeepc 1101ha.

    ho creato il file /etc/grub.d/01_915resolution e aggiunto le seguenti righe:

    echo insmod 915resolution
    echo 915resolution 58 1366 768 32

    poi ho creato /etc/default/grub e aggiunto le seguenti linee

    GRUB_GFXMODE=1366x768x32
    GRUB_GFXPAYLOAD_LINUX=1366x768x32

    il tutto per utilizzare il framebuffer ed avere sia la console tty che il server X con una risoluzione di 1366x768 e il direct rendering

    quindi utilizzo il seguente xorg.conf

    la console funziona perfettamente e al primo tentativo anche il server X. il device /dev/fb0 viene creato all'avvio ma il server X ora mi dà il seguente errore (posto solo l'errore e non tutto il log):

    (EE) FBDEV(0): FBIOBLANK: Invalid argument
    (==) FBDEV(0): Backing store disabled
    (II) FBDEV(0): DPMS enabled

    in pratica il problema sta in:
    (EE) FBDEV(0): FBIOBLANK: Invalid argument

    il server si avvia comunque ma con una risoluzione 1024x768 (che in uno schermo piccolo come il mio è uno scempio) e senza direct rendering.

    ho letto in giro che un errore simile era presenta nel port per sparc di debian lenny ed è rimasto un bug irrisolto.

    help me please!!!!
    vi ringrazio anticipatamente

    Default Riferimento: problemi con scheda video Intel Corporation System Controller Hub (SCH P

    ciao, io avevo un probema simile, praticamente mi si avviava a 800*600 senza possibilità di alzare la risoluzione, anche se con un chip video differente la soluzione potrebbe essere la stessa (probabilmente entrambi usano il driver vesa)
    non sono espertissimo ma seguendo una guida (molto generale) trovata su internet ho risolto così:
    cp /etc/X11/xorg.conf-vesa /etc/X11/xorg.cong
    ho riavviato ed è andato

    Default Riferimento: problemi con scheda video Intel Corporation System Controller Hub (SCH P

    grazie per la risposta....io comunque ho già la risoluzione 1024x768, il mio problema è avere una risoluzione 1366x768 (che avevo con ubuntu e driver poulsbo). se guardi il post sto usando "fbdev".
    Data la carenza di risposte credo che gli utenti più esperti abbiano pensato che il problema sia già stato risolto in altri thread.....in effetti non è così: tutte le soluzioni già proposte non sono valide (nel repository ppa tutti i driver sono funziananti solo con versioni dell'xserver successive a quella installata in bt r2).
    Fatevi vivi....grazie

    Hai ragione sembra che il fix vesa funzioni solo fino a 1024, comunque qua c'è chi ha risolto

    prova a dare un occhiata
