problemi grafici con ubuntu 18.04

[Grumpos]

Buongiorno,
Da qualche tempo ho installato sul mio notebook ubuntu 18.04. Ho notato due problemi:
1. I video (soprattutto su youtube ) si freezano per un instante (circa 1s) un po' a random. Solo il video, l'audio continua
2. Firefox ha dei glitch grafici (non sempre, ma spesso) nella zona della barra degli indirizzi/schede: si formano dei "quadrati" di vario colore/grandezza ad intermittenza, tipo zone corrotte.

Il notebook è un lenovo thinkpad e570, i5 7200u+gpu integrata+16gb ram+nvme intel con win10 + sata samsung 860 evo con ubuntu.
Il pc aveva inizialmente 8gb ai quali ho aggiunto un altro banco da 8 sempre della lenovo.

Qualche idea? Ho provato a cercare in rete ma non trovo nulla che risolva questi problemi

[monte.cristo]

In genere questo tipo di problemi sono legati ai driver della scheda video.
Posta il rusltato del comando
sudo lshw
così è possibile rendersi conto dell'hardware del pc.

[Grumpos]

Intanto grazie,
Ecco il risultato del comando (è bello lungo)

Non conosco il portatile, ma in base a quanto postato, il pc usa la scheda grafica integrata che su quel processore è una Hd 620
Quando specifichi "grafica integrata" ti riferisci a quella oppure ha anche un'altra scheda video?
Se hai solo quella scheda video, non so quanto si possa fare perchè purtroppo i driver per le schede video Intel non brillano per performance. Io, su un muletto che ha una cpu decisamente più scarsa della tua, ho installato lubuntu e, grazie alla richiesta più limitata di risorse di lxde rispetto a gnome, non ho praticamente più lag.

[Grumpos]

il notebook ha solo quella integrata (la 620)
Mi sembra strano che non ce la faccia. Sul vecchio portatile avevo un i3 390m sempre con integrata e non avevo problemi (linux mint 17.1) :(

[sacarde]

come sta' la CPU quando accade questo?


con: top

[Grumpos]

E' un ora e mezza che guardo video sul tubo e niente...non si blocca. :muro:
Con top ho web content che prende circa il 70-80% di cpu e firefox il 28
Ho usato anche monitor di sistema che dice che uso tra il 50% e il 60+% per tutti i 4 "core" durante la riproduzione video.

Noto anche che la riproduzione non è sempre "fluida" anche con i video a 720p60fps

[Grumpos]

Dopo qualche giorno si è ripresentato il problema:
durante il video la cpu, con top, varia tra i 70 e i 130% ma non c'è differenza quando avvengono i freeze. Anche con il monitor di sistema non ci sono picchi o altro (stabile tra il 50-60% per tutti i core) :(

Ho visto che firefox e chrome non utilizzano l'accelerazione hw, al contrario di vlc/mpv (la cpu sta su 15%)

Non riesco invece a capire da cosa derivano i glitch su firefox (solo firefox fa questa cosa)

[sacarde]

purtroppo con le nuove release a volte ci sono problemi, consiglio 2 cose, innanzitutto potresti disabilitare gli effetti grafici, se hai ubuntu liscio dovresti trovarli nel menù aspetto (appereance) e magari la cosa si risolve...

oppure, aggiornare i driver video usando un ppa come questo qui:
https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa
è un cambiamento più radicale ma di solito risolve la maggior parte dei problemi. so che il thinkpad in oggetto funziona perfettamente con ubuntu, anche se la certificazione per il momento la ha solo ubuntu 16.04 perchè la 18.04 è uscita da poco.

Più che altro intendevo l'accelerazione video, visto che la cpu sui video da browser schizza via. Su chrome sulla scheda about://gpu ho la voce video decode su Unavaiable e rasterization su software only.

Oggi 10:41


Provo a vedere se risolvo...avevo scelto il thinkpad + ubuntu visto che aveva appunto la certificazione :rolleyes:
