Problema risoluzione schermo ASUS L3000 [RISOLTO]

[it9ybg]

Salve, dopo esser riusciuto a installare Xubuntu sul mio ASUS L3000, al riavvio ho notato che la risoluzione dello schermo rimane bloccata a 640 x 480, quindi mi ritrovo un desktop con icone grandi e antipatico da gestire, specialmente pagine web con Firefox. Premetto che, nella precedente installazione, la 8.04 non riscontravo questo problema. Dopo aver capito come risolvere l'errore GRUB all'avvio, ho deciso di installare l'attuale versione (14.04 Xubuntu) dal CD.
Nelle impostazioni del sistema non riporta driver proprietari e, sperando possa risolvere il problema, chiedo a VOI esperti un aiuto. Grazie anticipate...

Prima di tutto vediamo che scheda grafica è installata:

Codice: Seleziona tutto

 lspci | grep -i vga

ho visto che ci sono varie sigle per il tuo pc, posta anche il comando:

sudo lshw

Ho inserito anche il codice

Codice: Seleziona tutto

sudo nano /etc/X11/xorg.conf

riportato in questa risposta, ma forse tocca modificare qualcosa, purtroppo non và...

http://forum.ubuntu-it.org/viewtopic.php?f=30&t=590875

[Ubuntello]

Ciao it9ybg,

innanzitutto assicurati che la prima risoluzione disponibile dopo "Modes", nel file xorg.conf, sia quella giusta per il tuo monitor. Poi dai il seguente comando per eliminare l'eventuale file creato dall'interfaccia grafica per le impostazioni del monitor, che interferirebbe con la configurazione manuale:

Codice: Seleziona tutto

rm -f $HOME/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml

Attenzione: dopo aver fatto ciò, non dovresti modificare in alcun modo le impostazioni del monitor tramite il programma per la gestione dello stesso che trovi in Xubuntu, altrimenti il file verrebbe ricreato e dovresti dare nuovamente il comando.

Adesso riavvia per vedere se la risoluzione è quella corretta. Se non dovesse funzionare, riporta qui il risultato di:

Codice: Seleziona tutto

for file in /etc/X11/xorg.conf{.d/*,}; do [ -s $file ] && echo -e "\n$file:"; cat $file; done


Per vedere se c'è qualcosa che non va nei file di configurazione.


Nota: per chi avesse lo stesso problema e non utilizza Xubuntu (XFCE), ma usa GNOME ad esempio, dovrà sostituire il primo comando del mio messaggio con:

Codice: Seleziona tutto

rm -f $HOME/.config/monitors.xml

[it9ybg]

Grazie per la risposta e dell'aiuto... Purtroppo non và, ho provato a inserire le due risoluzioni più basse (prima una e poi l'altra) ma rimane sempre la 640x480
Ti allego il file... sono nelle vostre mani!!!

Quello che più risalta, nel file xorg, è questo:

VertRefresh 50-120

il 120 mi sembra esagerato per un tft. Controllo e poi vediamo

[it9ybg]

Ok aspetto con ansia vs risposte...sono bloccato, nn sò cosa fare più!! Grazie anticipate!

[Roberto Pontecorvi]

Prova a cambiare:

VertRefresh 50-120

in:

Codice: Seleziona tutto

VertRefresh   56-86

Mi posti ache il risultato del comando:

Codice: Seleziona tutto

lshw

Controlla dal gestore pacchetti se è presente "arandr"

[it9ybg]

Nulla...ancora non và... Arandr non presente!
Ti posto il comando lshw

Ho anche installato Arandr, ma anche lì la risoluzione rimane 640x480 e non mi dà altre alternative!

[Roberto Pontecorvi]

Proviamo a forzare la risoluzione. Posta il risultato di:

Codice: Seleziona tutto

xrandr -q

e

Codice: Seleziona tutto

cvt 1024 768

Se la risoluzione che vuoi sia 1024x768, se no al comando cvt metti la risoluzione da te voluta.

[it9ybg]

Nulla... riporta che la massima risoluzione è 640x480, possibile?
Comunque ho notato che al comando

Codice: Seleziona tutto

  sudo nano dpkg-reconfigure xserver-xorg

, il file è vuoto, forse tocca inserire il codice qui? non vorrei fare danni all'avvio!
