Det gremmer meg at Canonical lar quicklists ligge brakk.. Høyreklikk på programikon er fullstendig ubrukelig til sentrale apper som LibreOffice. I Win7 på jobben bruker jeg høyreklikk hele tiden for å åpne nylig brukte dokumenter. I Unity er all sånn snazzy funksjonalitet overlatt til communitiet, uten noen som helst fremdriftsplan.

 

En annen ting er at quicklists for webapps bare fungerer når programmet kjører..

Chromium og javascript lekke minne? Aldri hørt om. Ca. like mange tabs (50 +/-) og oppetid.

Og der har vi synderen. Du ser helt riktig. 2GB for en enkel fane.

Det skal sies at sharelatex virker å være ganske tung, men god damn. Om jeg f. eks lukker fanen og starter den på nytt resettes alt. Stusser bare litt over at det aldri tømmes noe og derfor bruker latterlig mye minne etterhvert.

Sliter med ustabil tilkobling til Eduroam, både at jeg faller ut eller ikke får koblet til. Har hatt laptopen i ca. 2 år og har vært perioder hvor det har fungert uten problemer og andre hvor det har vært latterlig ustabilt. Bruker rimelig standard oppsett med (Gnome) NetworkManager og wpa_supplicant (Crunchbang) på et Broadcom nettverkskort.

Tror ikke det er relatert til nettverkskortet da det funkerer helt fint både hjemme, hos foreldrene mine samt hotspot på Android. Virker å være pga. den sliter med associating (authentication?), men hva kan være årsaken til dette? Har blandede følelser når det gjelder Eduroam, men samtidig så fungerer det fint for de fleste på Windows så kan godt være på min side. Kan dette være pga. Windows er mer aggressiv på å bytte channels om nødvendig og lignende (uten nødvendig krav om autentisering)?

Har tidligere brukt WICD, men syns ikke den er stort bedre enn NetworkManager pga. måten den skiller channels gjør den vanskelig å bruke på et nettverk med veldig mange channels. Virker uansett å være relatert til wpa_supplicant.

Eduroam kan bruke sertifikater, men det som er tilbudt virker å være ugyldig. Samtidig virker det å fungere like bra/dårlig uansett om det brukes Tunneled TLS eller PEAP.

Merk linjene med "-->". Har forøvrig fjernet timestamp og hostname for at det skal være enklere å lese. Søkt litt på "CTRL-EVENT-ASSOC-REJECT status_code=16" men finner nesten bare ting relater til mobiler.

Har du prøvd å bruke sertifikat? Eduroam pleier å fungere ganske knirkefritt hos meg med GTE Cybertrust Global Root sertifikat. Finnes under /usr/share/ca-certificates/mozilla.

Når jeg sier ganske knirkefritt, så er det fordi det hender at det detter ut én eller to ganger i løpet av en lang dag hvis aksesspunktet er crowded. Men om dette har med Ubuntu å gjøre eller noe annet (hardware, aksesspunkt, osv.) vet jeg ikke. Tilkoblingen pleier å komme opp igjen ganske kjapt etter at det faller ut.

Bruker Intel 6300 trådløskort.

Skal innrømme at det begynner å bli en stund siden jeg har prøvd sertifikat, men mener å huske at det var ugyldig og derfor ikke fungerte i det hele tatt. Har fungert lenge i perioder uten noe sertifikat.

 

Begynte å bli litt desperat etter konstant disconnects så postet det jeg hadde fått med meg i håp om at noen hadde vært borti samme feilmelding/situasjon. Derimot nå ser det ut til å være en periode med stabilitet, som jeg trengte for noe skolearbeid. Kommer tilbake med mer info når/om det begynner å disconnecte som en gal igjen og da kan jeg prøve å titte på sertifikatet du nevner :)

 

Er derimot fortsatt nysgjerrig på hva den feilmeldingen egentlig indikerer. Er det feil på min side (client) eller er routern kranglete? Av de "løst" trådene jeg har funnet har det fungert for folk som har restartet routern.

 

Edit: Disconnected igjen. Prøver med sertifikatet. Men hvorfor tror du det skulle påvirke noe særlig egentlig? Mtp. jeg disconnecter random og det fungerer litt hipp som happ om jeg får koblet til eller ei.

 

Edit2: Som forventet kan jeg ikke merke noen forskjell. Når jeg har vært på skolen har jeg hatt nok annet å gjøre og derfor kjørt kabel/wifi hotspot om det har vært krise. Når/om jeg finner ut av det kommer jeg med mer info/fix.

Har skaffet meg en VPS fra Digital Ocean med SSD. Helt greie hastigheter, særlig mtp. jeg betaler $5/month.

Jeg har ingen erfaring med ndiswrapper, men i utgangspunktet er jeg veldig skeptisk. Har du virkelig inget annet alternativ altså? Hvilket kort har du? Ellers kan det lønne seg å stille litt mer spesifikke spørsmål enn å kun etterspørre hjelp. "Don't ask to ask" osv. Hva har du prøvd?
