Dotaz: LightScribe v Gentoo

[Václav HFechs Švirga]

Dobrý den, pořídil jsem si vypalovačku (LG GSA-H12L) s podporou LightScribe (potisk speciálních cd laserem) a i když se dá o užitečnosti pochybovat, řekl sem si že stejně tento úžasný zázrak vyzkouším. Koupil sem si speciální medium a začal googlit jak v linuxu na to.

Dostal sem se k ovladačům od Lacie a HP (prakticky to samé, jen má HP novější verzi) v rpm (bohužel v ničem jiném, proprietární bastl). Přes rpm2tar jsem to nějak prasácky nainstaloval, včetně kreslících softů (jak od lacie, tak od hp) a jal se to vyzkoušet.

A zde nastal problém. Při detekci mé mechaniky dojde vždycky k SIGSEGV chybě a konec. Přes strace jsem dostal toto:

Pomocí google jsem nedospěl k ničemu. Pochopil jsem, že někomu to funguje, a snad není ani problém v /proc/sys/dev/cdrom/info (který mi mimochodem opravdu odkazuje na DVD vypalovačku, po přepojování IDE kabelu).

LightScribe jsem zkoušel se dvěmi jádry, obojí 2.6.19-gentoo-x. Někde na stránkách lacie (hp uvádí supported 2.6) jsem četl něco o 2.6.17 (ještě jsem netestoval), ale zase kvůli takové blbosti se na jedno jádro fixovat nehodlám. Do systému mi to rpmko žádný jaderný modul nedostalo, jenom knihovna a pár dalších souborů.

Pro upřesnění udám ještě konec výpisu aplikace od HP (velmi podobné).

No ja nevim, tady jsou nejaky ebuildy, jinak me tahle blbost nezaujala...

[Václav HFechs Švirga]

Díky, tyhle ebuildy sem nenašel. Právě se mi to instaluje, uvidím.

[DNA]

pouzivej popisovac, ty vychytavky vyjdou draho uz na mediu a cert vi, jak dlouho budou v prodeji...

[Ahmed]

Popisovačem to nikdo tak hezky neudělá pokud nejsi umělec Moh bych ti ukázat jak škrábu já, pochopil bys Navíc mechaniky s Lightscribe jsou dost rozšířené, stojí mnohdy skoro stejně a média stojí to samé co klasická CD před pár lety...

Light Scribe = hovadina nejvetsi!!!
