[Risolto] Impossibile regolare luminosità. HP 6735s ATI HD3200

dongennaro · 10 Maggio 2020, 11:05am

Salve.
Come da titolo, non riesco a regolare la luminosità (argh, sto diventando cieco).

Uso fedora 16 32bit con KDE.

usando i tasti fn + f7 o +f8 non succede assolutamente nulla (mentre con l’audio funziona)

Anche se cerco di cambiare la luminosità nel profilo energetico (qualunque esso sia) la luminosità non cambia.

Vi riporto alcuni comandi che sicuramente mi chiederete (PS: Ho installato i driver ufficiali) :

Ci avevo già provato! l’ho letta in giro questa cosa (anche in questo forum) purtroppo per me non ha funzionato

virus · 10 Maggio 2020, 11:05am

se dai un:

# yum install xbacklight

e lo lanci

# xbacklight -set 80

ti aumenta la luminosità ?

No, la risposta è

No outputs have backlight property

ok.

Non riesco a capire cosa è successo…ma ora la luminosità è al massimo, anche se non mi permette comunque di regolarla.

Provo a rifare tutti i comandi che mi hai suggerito e vediamo se riusciamo a venire a capo di qualcosa.

allora:

[root@localhost vito]# yum update bash Plugin abilitati:langpacks, presto, refresh-packagekit adobe-linux-i386 | 951 B 00:00 rpmfusion-free-updates | 3.3 kB 00:00 rpmfusion-nonfree-updates | 3.3 kB 00:00 updates/metalink | 26 kB 00:00 Impostazione processo di aggiornamento Nessun pacchetto marcato per l'aggiornamento [root@localhost vito]#

mentre

xbacklight -set 80

Ne aumenta ne diminuisce la luminosità ma a differenza di prima non da un messaggio d’errore.

Questo è tutto… qualche idea?
Ma come faccio a capire se ho installato bene i driver della scheda video? Magari il problema è quello?

virus · 10 Maggio 2020, 11:06am

la magia non è una parola inclusa nel dizionario linux.

hai fatto, od installato qualcosa, tra il momento in cui non funziona quello in cui funziona ?

dongennaro · 10 Maggio 2020, 11:06am

ahahah hai ragione!!

Ho solo “smanettato” con “AMD catalyst control center” (sinceramente non ricordo cosa ho cambiato, anche perché ogni cambiamento che facevo fisicamente non mi riportava niente…poi dopo il riavvio invece la luminosità è al massimo!

Il problema resta lo stesso però…non la posso regolare!

Edit: Ho riavviato…e la luminosità è ritornata al minimo

dongennaro · 10 Maggio 2020, 11:06am

Ragazzi, un aiuto…veramente! Sto diventando cieco così!

Edit: Sto diventando scemo. E’ ritornato tutto come prima -.-" non ho più nessun risultato con ls /sys/class/backlight il cat dice che non esiste più niente in /sys/class ecc ecc

virus · 10 Maggio 2020, 11:06am

il problema è che stai andando alla cieca.

puoi essere più ordinato negli interventi e farci capire qualcosa ?
così non riusciamo ad aiutarti.

comincia col postare da root

[code]# lspci -nn

ps. non riavviare a casaccio, fallo solo se te lo diciamo.

Non è che riavvio a casaccio, riavvio quando ne ho bisogno o quando devo spegnere il pc (per passare a windows per lavorare o per qualsiasi altro motivo!)
Il problema è che ad ogni accensione si comporta in modo diverso. Ora la luminosità è di nuovo al massimo (ma non posso regolarla)

Edit:

in giro mi hanno detto di controllare questo :

visto che in cooling_device5 ce un riferimento alla scheda video, mi hanno detto di creare questo script:

[code]
cat bin/brightness
#!/bin/bash

backlightd=/sys/devices/virtual/thermal/cooling_device5
file=cur_state
max=max_state
level="$1"
if -n “${level}” ]; then
“${level}” -ge 0 ] || level=0
max_level=cat ${backlightd}/${max} &&
“${max_level}” -gt 0 ] || exit 91
${level} -le ${max_level} ] || level=${max_level}
sudo sh -c “echo ${level} > ${backlightd}/${file}”
fi

cat ${backlightd}/${file}

exit[/code]

Ovviamente ancora non ho provato! Ho detto che aspetto te e lo farò =)…!

se prendi informazioni destra a manca senza criterio, confondi te e confondi noi.

dacci invece da root:

# tree /sys/class/backlight/acpi_video0

Scusami, sono stato tanto (troppo) impegnato con il lavoro.

Non è che prendo info a destra e a manca senza criterio, sono informazioni che vengono da un forum di fedora (in inglese) riguardanti il mio portatile o comunque molto simili.
Ma siccome non ci sto capendo una ceppa allora smetto di prendere informazioni, ti listo tutto ciò di cui hai bisogno, mi affido a te.

[code][root@localhost media]# tree /sys/class/backlight/acpi_video0

PS: Buon natale (anche se in ritardo) e buon fine anno!

metti l’opzione:

acpi_backlight=vendor

all’avvio in questo modo:

# gedit /boot/grub2/grub.cfg

aggiungila alla linea linux, salva chiudi.
dai un reboot, posta:

# tree /sys/class/backlight

vediamo anche l’output di:

vuoi controllare anche sul sito del produttore se è presente una versione aggiornata del Bios ?
