Pc va a scatti! Aiuto utente alle prime armi

Post by Pensiero » Mon Apr 09, 2018 1:45 pm

Ciao a tutti, vi spiego il mio problema.
Dopo aver assemblato il mio nuovo computer ho deciso di fare il passo e non comprare la licenza Windows per fare finalmente il salto nel mondo Linux.
Volevo chiedere se riuscite a darmi una mano perché non riesco a far girare il sistema operativo. Il problema è che va tutto a scatti, già sul desktop soltanto muovendo il mouse e selezionando una cartella. Firefox scatta semplicemente scrollando la pagina e i video su youtube sono inguardabili per la lentezza.
Segnalo anche che la ventola della cpu gira sempre al massimo nonostante il processore sia a 45° (temperatura rilevata da Bios).
Ho già aggiornato il Bios della scheda madre all’ultima versione, ho provato Ubuntu Mate 17.10, Fedora Cinnamon 27 e Linux MInt 18.3
La mia configurazione è:
CPU: Intel i3-8100 65W TDP

SSD: SAMSUNG 960 EVO NVMe M.2

Ram: CRUCIAL Sport DDR4 2400 8GB

MB: ASRock Z370M-ITX

PSU: Corsair RM550x

Monitor: Eizo ev2455 1920x1200

Essendo la scheda video integrata penso che il problema siano i driver del processore
Se può essere utile allego anche l’output del commando sudo lshw:

Code: Select all

Ho risolto seguendo questa guida:
https://askubuntu.com/questions/989946/ ... le_rich_qa

Code: Select all

    1. Do sudo vi /etc/default/grub or use any other editor.
    
    2. Find GRUB_CMDLINE_LINUX_DEFAULT line and add i915.alpha_support=1 to its value. 
        It'll look like GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.alpha_support=1"
    
    3. sudo update-grub and reboot.
 
 Ps. in realtà non so perchè non mi faceva modificare il file quindi una volta aperto con il tasto destro come amministratore l'ho modificato e salvato e poi ho eseguito l'ultimo comando.   
Ma come spiegano qui non sembra la miglior soluzione:

Ora funziona tutto bene a parte un piccolo lag video (quando scrollo velocemente una pagina appare una riga di discontinuità nell’immagine).

Mi sembra di aver capito che sto utilizzando dei driver provvisori c’è un modo migliore per risolvere?
