fastidiosi problemi

[dariohq]

Salve a tutti.

come da titolo..il sistema funziona ma ci sono alcuni piccoli problemi che vorrei risolvere ma non trovo una soluzione anche perchè non sono un utente esperto.
I problemi sono 4 e li elenco qui sotto in base all'importanza

premetto che il mio è un pc fisso AMD Athlon 64 X2 5200+ 4 GB di ram DDR2 Hard Disk 320 GB Scheda video Geforce GT520 2 GB DDR3 e UBUNTU 12.04 64 bit
è collegato a un monitor 22" FULLHD infatti ho impostato la risoluzione a 1920x1080



1 - Ho google Chrome versione 22.0.1229.94 e una Webcam Microsoft LifeCam HD 3000. Ebbene quando visualizzo un sito con animazioni flash che sia youtube o altro la spia della webcam inizia a lampeggiare! E quando apro un programma tipo Cheese o Camorama l'immagine si blocca dopo un secondo (letteralmente)
Ho provato a disinstallare completamente Chrome e reinstallarlo ho disattivato tute le estensioni ma niente da fare o utilizzo chrome o la webcam. Questo NON succede nè con Opera nè con firefox (dove la webcam funziona con tutti e due i programmi)


2- Qualche giorno fà avevo una scheda video nvidia GT9500 512 MB che ho cambiato con l'attuale nvidia GT520 con 2 GB. Prima di cambiare la scheda ho disinstallato i driver e , una volta montata quella nuova, li ho reinstallati.
Tutto funziona bene l'unica cosa che con la vecchia GT9500 editando il file xorg.conf (aggiungendo in una specifica riga Option "Coolbits" "1" ) potevo "overcloccare" la scheda dal programma NVIDIA X Server Settings nella voce "Clock frequencies".
Ebbene con quella nuova non riesco più ad abilitare questa opzione.
Per caso è la scheda video che non può essere overcloccata o un problema di driver? (versione 295.40)
il programma NVCLOCK non funziona (vabbè non funzionava neanche con la vecchia scheda video).

3- un mese fa acquistai tramite ubuntu software center il gioco "Amnesia the dark descent"
tutto bene...fino a qualche giorno .
Prima quando avviavo il gioco compariva inizialmente una finestra "launcher" dove potevo settare i parametri di grafica, sonoro ecc.. e poi avviare il gioco vero e proprio. Adesso quando provo a far partire il launcher l'interfaccia grafica di Ubuntu crasha (sia Gnome che Unity anche senza gli effetti grafici) e ritorno alla schermata di LOGIN. Spulciando nella cartella del gioco ho trovato i file "Amnesia.bin64" e "Launcher.bin64" il primo fa partire il gioco senza problemi il secondo genera questo problema (che prima non si verificava).
Qualcuno puo darmi un suggerimento per capire cosa non funziona?
Provato anche a disinstallare e installare il gioco ma il problema persiste.

4- Volevo testare la webcam su Facebook tramite l'opzione "aggiungi foto/video" e poi "tramite webcam" purtroppo sia su firefox che su opera compare solo un'animazione di caricamento e la webcam non viene riconosciuta. Qualcuno conosce un modo per risolvere il problema?
Su Chrome la webcam sembra funzionare ma l'immagine si blocca dopo un secondo (penso sia legato al problema numero 1)

Non sono problemi gravi e alcuni sono facilmente aggirabili ma se li volessi risolvere qualcuno può darmi qualche dritta o suggerimento?
Ovviamente cercando su google non sono riuscito a trovato nulla
Grazie a tutti :-)

non sono un programmatore ma azzardo

secondo me è un conflitto d'uso della webcam tra flash (che può avere accesso a tale periferica) e cheese

cosa proverei a fare

prendi un animazione in flash, clicca col destro e seleziona inpostazioni globali, da li li dici di non usare la webcam, forse si risolve.

per il 3 prova a lanciare quello che ti da problemi da riga di comando e a postare l'output

[dariohq]

grazie per le risposte

comunque su chrome se vado su "impostazioni globali" mi apre una nuova scheda e va sul sito di flash player.
invece su "impostazioni" mi apre una finestra e lì posso negare l'accesso alla videocamera e microfono solo che il problema persiste. (la versione del flash player su chrome è la 11.4.31.110)

per quanto riguarda Amnesia ho provato ad avviare il file "launcher.bin64" da terminale purtroppo l'interfaccia grafica si riavvia e non riesco a postare l'errore

grazie comunque per i suggerimenti.

Ragazzi ho notato una cosa.

Il crash dell'interfaccia e ritorno alla schermata di Login lo fa anche in altre due situazioni


- quando accedo a unity 2d e premo l'icona "dash" (la prima icona del menu di unity)
non succede con unity 3d ma l'icona viene chiamata "Home"

- lo fa anche con Konqueror

posso eventualmente fare un filmato postarlo su youtube e aggiungere il link a questo forum?

Ragazzi riprendo il topic per cercare una soluzione a un fastidioso problema..cioè il crash dell'interfaccia grafica e ritorno alla schermata di login.
sopra avevo scritto che capitava con il gioco amnesia...ebbene LO STESSO problema succede quando accedo alle impostazioni di un programma come vlc.
Per esempio apro VLC - poi su STRUMEMNTI - poi PREFERENZE - poi AUDIO e poi appena clicco su MODULO di USCITA ecco che la schermata diventa nera e ritorno alla schermata di login.
Vi posto il file /var/log/syslog non ci capisco molto... se qualcuno può darmi una mano perchè succede con altri programmi e sinceramente non mi và di formattare e reinstallare ubuntu.


questo è quello che capita quando sono andato nelle impostazioni di VLC alle 22.16 (primi secondi)
