Nový hw - bugy

Chyby v hw sú častý problém v sfére počítačov. Niektoré chyby sú spôsobené neumyselnou chybou. Niektoré obyčajným šetrením na vývoji.

Chyby na úrovni sw sú tiež časté ale je ich možné vyriešiť aktualizáciou jadra.

Chyby

Náhle vypadnutie podporovaného rozlíšenia.

Pod pojmom vypadnutia rozlíšenia rozumieme stav v ktorom podporované rozlíšenie nie je možné nastaviť. Tento jav nastal pri prebudení z uzamknutia obrazovky tesne pred uzamknutím.

Pád procesu amdgpu

Pád procesu nastal pri pokuse o prebudenie z uzamknutej obrazovky s následným odpojením grafického výstupu. Systém bol bez akejkoľvek možnosti prepnutia na tty.

Záver

Aktualizácia

Pravdepodobne boli tieto problémy spôsobené novým jadrom v backport repozitári. Vrátil som predchádzajúcu verziu jadra.

Z dôvodu, že firmvér apu je v nonfree repozitári, tak nemá zmysel hlásiť chybu distribúcii.

V každém případě tohle není hw bug, ale nějaká chybka v driveru. Nejspíš dal někdo free do špatný větve podmínky. To bude opravený rychle (když to nahlásíš tak ti rovnou možná i pošlou patch).

Ale jo, i tohle sem patří, takové tvítnutí. Aspoň někdo je paličatý a pro něj objev zveřejní a nese kůži svou na trh.
I to je cesta, jak psavce přivést k psaní, ke ztracení ostychu a tak.

Každý je nějaký, něco dělá radši a něčemu se zase vyhýbá.
I ten největší psavec snad nějak začínal, po malých krůčcích. I když asi ne veřejně :-)

Takže tohle je snad ta malá kapička, která přispěje k budoucímu dešti, dešti bohatšího AbcL :-)
