Φωτεινότητα οθόνης

[Mike91]

Γεια σας.
Όταν ανοίγω το pc και μπαίνω στο ubuntu η φωτεινότητα της οθόνης είναι στο μέγιστο. Εγώ την αλλάζω και την βάζω περίπου στην μέση αλλά την επόμενη φορά που μπαίνω στο ubuntu η φωτεινότητα είναι ξανά στο μέγιστο. Υπάρχει κάποιος τρόπος να την κάνω να μην αλλάζει και να είναι πάντα στην μέση;

Περίμενα μήπως κάποιος απαντήσει σε αυτό το πρόβλημα γιατί οι λύσεις που έχω εγώ είναι λίγο περίεργες, δεν μου αρέσουν πολύ και ίσως να υπάρχει κάτι πιο απλό.

Η πρώτη λύση είναι να εγκαταστήσεις το πακέτο laptop-mode-tools μέσω synaptic και να κάνεις τις κατάλληλες ρυθμίσεις στο: /etc/laptop-mode/laptop-mode.conf
Δεν θα μπω σε λεπτομέρειες "πως" και "γιατί", επειδή δεν είναι αυτή η λύση που σου προτείνω. Το αρχείο αυτό περιέχει και άλλες ρυθμίσεις που καλό είναι να μην πειράξεις.

Η δεύτερη λύση και αυτή που σου προτείνω ως προσωρινή μέχρι να απαντήσει κάποιος κάτι καλύτερο είναι η εξής:
Άνοιξε το τερματικό και γράψε:

Κώδικας: Επιλογή όλων

sudo gedit /etc/rc.local

Aφού γράψεις τον κωδικό σου και πατήσεις ENTER θα ανοίξει ένα καινούριο παράθυρο του gedit που θα γράφει κάτι τέτοιο:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0

Πριν το "exit 0" γράψε: echo 7 > /sys/class/backlight/acpi_video0/brightness όπου ο αριθμός 7 είναι το επίπεδο φωτεινότητας μεταξύ του 0 και του 10. Βάλε ότι επίπεδο σε βολεύει. Μετά από αυτό, το κείμενο στον gedit θα είναι αυτό:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo 7 > /sys/class/backlight/acpi_video0/brightness
exit 0

Πάτα save, κλείσε το παράθυρο και το τερματικό και μετά από κάθε restart που κάνεις η φωτεινότητα λογικά θα είναι στο επίπεδο του αριθμού που έβαλες στο echo.

Άμα δεν σε ικανοποιεί αυτό (εμένα δεν θα με ικανοποιούσε), περίμενε μήπως κάποιος σου απαντήσει κάτι πιο σταθερό και μόνιμο.

EDIT: Υπάρχει και η επιλογή να ρυθμίσεις την φωτεινότητα μέσα από το BIOS.

AYTH EINAI ΜΙΑ ΠΡΟΣΩΡΙΝΗ ΛΥΣΗ ΓΙΑΤΙ ΔΕΝ ΔΙΟΡΘΩΝΕΙ ΑΚΡΙΒΩΣ ΤΟ ΠΡΟΒΛΗΜΑ. ΑΠΛΑ ΑΛΛΑΖΕΙ ΤΗΝ ΤΙΜΗ ΤΗΣ ΦΩΤΕΙΝΟΤΗΤΑΣ ΚΑΤΑ ΤΗΝ ΕΝΑΡΞΗ.

Είναι μάλλον πρόβλημα στο BIOS του υπολογιστή σου. Ανάλογα με τον υπολογιστή, η φωτεινότητα μπορεί να καθορίζεται από το BIOS.
Για να το διαπιστώσουμε, δώσε το αποτέλεσμα της εντολής dmesg.

Αυτό που λέει ο eliasps το έκανα αλλά δεν είδα καμία διαφορά

[Learner]

Κάνε μια επεξεργασία στο παραπάνω μήνυμα σου (απότελεσμα dmesg) και βάλε το αποτέλεσμα μέσα σε code tags.

Κώδικας: Επιλογή όλων

[code]το αποτέλεσμα εδώ[/code]

Απ' ότι βλέπω , έχεις εγκαταστήσει τον κλειστό οδηγό της Ati. (fglrx) . Αν θες μπορείς να δοκιμάσεις να εγκαταστήσεις τον τελευταίο οδηγό , μέσω PPA(αποθετηρίου). Δηλαδή δεν υπάρχει ο οδηγός(driver) αυτός στα επίσημα αποθετήρια του Ubuntu .

Ανοίγεις ένα τερματικό και γράφεις τις παρακάτω εντολές μια-μια.

Κώδικας: Επιλογή όλων

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install fglrx

Κάνεις μια επανεκκίνηση και κοιτάς μήπως έφτιαξε.

Αν τυχόν παρουσιάσει πρόβλημα.. (δεν δουλεύει - μαύρη οθόνη κλπ. ) τότε απεγκαθιστάς τον παραπάνω οδηγό(driver) με τις εξής εντολές

Κώδικας: Επιλογή όλων

sudo apt-get install ppa-purge
sudo ppa-purge ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get dist-upgrade

Κάτι που ανακάλυψα πρόσφατα:

Αν χρησιμοποιείς το jockey για να δοκιμάσεις τον κλειστό οδηγό, τότε ο κλειστός οδηγός εγκαθίσταται στο σύστημά σου.
Και παραμένει φορτωμένος στο σύστημά σου. Παραμένει φορτωμένος ακόμα και αν επιλέξεις μετά τον ανοιχτό οδηγό.

Δεν είδες διαφορά στη φωτεινότητα καθόλου; πχ εάν βάλεις echo 5;
Άμα το κάνεις αυτό που σου απάντησα παραπάνω, τότε στις ρυθμίσεις τις φωτεινότητας η μπάρα πάλι θα δείχνει ότι είναι στο μέγιστο ενώ στην πραγματικότητα η φωτεινότητα θα έχει χαμηλώσει. Επίσης, άμα την πειράξεις και την αφήσεις σε ένα άλλο ύψος πάλι μετά από restart θα δείχνει ότι είναι στο μέγιστο, ενώ η φωτεινότητα θα είναι μειωμένη, δηλαδή η διαφορά θα φαίνεται μόνο στο μάτι.
Αλλά άμα λες ότι δεν λειτουργεί τότε οκ. Θα κοιτάξω ακριβώς να σου γράψω οδηγίες για το laptop-mode-tools που ανέφερα παραπάνω αλλά απέφυγα να αναλύσω.
Στο μεταξύ μπες στο BIOS (μόνο αν ξέρεις τι κάνεις) και ψάξε για ρυθμίσεις φωτεινότητας, ίσως η λύση είναι εκεί.

eliasps λάθος δεν το είχα κάνει επανεκκίνηση και δεν φαίνονταν η αλλαγή, τώρα όμως το βρήκα, αλλά έχει προκύψει άλλο ένα προβληματάκι όταν κλείνω το pc κάνω τερματισμό στο ubuntu, εκεί που στην μέση της οθόνης βγάζει το σήμα του ubuntu μερικές φορές κολλά και δεν μπορώ να κάνω τίποτα. Πάντος σε ευχαριστώ για το άλλο.
