monitor che si spegne e si riaccende

[gnomix82]

salve, non so se sono nel forum giusto; in caso indicatemi quello più adatto...
Allora, il mio sistema operativo è Ubuntu (ultima versione), e il mio monitor è un LG FALTRON M2262D collegato alla scheda video tramite cavo vga.
Il mio problema è che spesso il monitor si spegne (come se vada in standby per pochi secondi) e poi si riaccende.
Perchè?

Se può essere utile, ecco l'output di alcuni comandi che ho dato da terminale:



$ lspci | grep VGA

[sacarde]

- lo fa a intervalli regolari?

- provato a cambiare i valori della sospensione, o disattivarla


- il monitor ha una funzione "risparmio energetico" ?

[gnomix82]

Innanzi tutto ho dimenticato di dire che con la precedente versione di ubuntu non avevo questo problema.

Lo standby si verifica ad intervalli non regolari. Ho l'impressione che lo faccia quando passo da una finestra all'altra, quando apro un menu, o sposto semplicemente il mouse.
Inoltre in fase di avvio (quando accendo il computer), invece lo fa sempre: va in standby per circa 10 secondi, e si riaccende un po' prima di vedere la scrivania di ubuntu.
Inoltre non so perchè nel mio computer non c'è più il file /root/xorg.conf in cui dicono si può modificare la frequenza (del monitor o della scheda video?).

Sospensione disattivata.

La terza domanda non l'ho capita.

[sacarde]

- usavi gli stessi driver video? (proprietari o liberi)


- xorg.conf era in /etc/X11/xorg.conf
per generarlo (anche se non serve piu'):

http://wiki.ubuntu-it.org/Hardware/Video/DomandeFrequenti#Come_si_riconfigura_il_server_grafico.3F



- pensavo fosse un problema del monitor e non del sistema

Mi sembra che usavo i driver proprietari; queste comunque sono le impostazioni attuali
http://tinypic.com/view.php?pic=6fyryt&s=9#.WG6CNWeYq5A
e anche selezionando la prima opzione non cambia niente

[sacarde]

proverei a usare i driver che usavi con l'altro sistema

li puoi installare anche a amano

http://wiki.ubuntu-it.org/Hardware/Video/Amd


*edit
ho chiesto, e in effetti per le 16.xx non ci sono piu' i driver proprietari "ati"

viene usato il "radeon" nel pacchetto:

xserver-xorg-video-radeon

Quindi cosa dovrei installare esattamente?
Scusa, ma non ho molta dimestichezza con i driver di linux, e non vorrei fare pasticci :)

[sacarde]

i driver opensource ci dovrebbero gia essere, lo vedi dal comando:



dpkg -l | grep xserver-xorg-video


una volta accertato, mi sembra non ci sia scelta o altro da fare
(fatto delle prove giocando con i valori della sospensione)


p.s.
la versione ubuntu dove funzionava bene, quale era?

Sospensione disattivata.
Mi sembra di averlo già scritto.


p.s.

La versione precedente a quella attuale (non ricordo esattamente i numeri).

[sacarde]

- prova una sospensione con tempo lungo


- per vedere se hai errori, esegui da terminale:
sudo systemctl --failed
e
sudo journalctl -b -p err


- era la 16.04 lts? (ha supporto di 5 anni)
la 16.10 ha supporto 9 mesi


- i driver radeon li hai installati e vengono usati, lo vedi da /var/log/Xorg.0.log

si

- i driver radeon li hai installati e vengono usati, lo vedi da /var/log/Xorg.0.log


certamente

[sacarde]

- volevo farti fare una prova immettendo il blocco dopo x minuti


- non vedo errori nei log riguardo il tuo problema


- non trovo i driver proprietari neanche per la 16.04
sei sicuro fosse quella?

nella videata non si vedono quali driver usa

ma il sistema lo hai ancora?

prova a vedere se trovi installati i driver proprietari ati/radeon

dpkg -l | grep fglrx



p.s.
sudo ubuntu-drivers devices

dovrebbe mostrarti i pacchetti installabili per i tuoi device

o hai fatto un aggiornamento di versione alla 16.10?


- i pacchetti "fglrx" che mi fai vedere sono di un: 15.10.2 ?

sei sicuro che sia un problema software e non hardware?

Hai provato a collegare il monitor ad altro pc?

Il monitor che si spegne e accende random potrebbe essere anche un condensatore o più che stanno finendo il loro ciclo di vita...
