Problemi uvcvvideo su Ubuntu 18.04 dopo Upgrade

[DRAGO.NET]

1) Quindi, se non dai quel comando non hai nessun problema e tutto funziona? Allora riavvia, non fare nulla e sei a posto
2) basta che elimini il file che ti ho fatto creare, con

Codice: Seleziona tutto

sudo rm /etc/modprobe.d/blacklist-uvcvideo.conf

Non è proprio così:
Se elimino il file che mi hai fatto creare la webcam torna a funzionare, però in fase di riavvio ho gli errori di uvcvideo come ho riportato nei thread precedenti.
Inoltre ultimamente dopo un aggiornamento ho problemi con la scheda di rete che non viene vista da un avvio a terminale spento; per vedere la scheda di rete devo riavviare da PC acceso.....

intanto elimino il file che mi hai fatto creare....per riavere la funzionalità della webcam e aspetto cosigli.

Infatti ne ho avuto la prova....
dopo l'eliminazione del file ho riavviato e non ho rete...

Io no, non saprei cosa consigliarti se non aprire un bug report.

Chi mi aiuta a aprire un bug report e vedere di risolvere

[DRAGO.NET]

ho messo Ubuntu Mate in dual boot con Ubuntu (unity) anche se preferisco di gran lunga Unity .

Con mia grande sorpresa il problema UVCVideo non ce l'ho.............


BHO!!!

chi me lo spiega???????

[DRAGO.NET]

Ho risolto!!!!!!!!!!!!!!!


Infatti è stato più semplice di ogni sforzo fatto per trovare la soluzione.......
Ho formattato....

Non ho più problemi, mi sono convinto a farlo dopo aver provato Ubuntu Mate senza problemi; quindi ho capito che il problema non era Ubuntu in sè ma qualcosa che avevo installato....
Non riuscendo a risolvere l'arcano problema ho formattato risolvendo.

[Roberto Pontecorvi]

Molto bene.

[DRAGO.NET]

ci risiamo...
Dopo il ripristino di ubuntu 18.04 mi ritrovo nuovamente col problema uvcvvideo descritto nei primi post...

Devo rinunciare a ubuntu Gnome e passare per sempre a Mate?

Questa è una tua scelta.

[DRAGO.NET]

Come fare diversamente?

[Roberto Pontecorvi]

Scusa nel primo post dici:

Devo fare una premessa: la mia webcam funziona....

.
Può essere qualche dipendenza che non và tanto d'accordo con ucc, nella versione "gnome".
