Hej (igen)

Jeg har stadig problemer med cd-brænding. Det er dog lykkedes mig at
kunne brænde som root, så nu er spørgsmålet bare hvorfor jeg så ikke kan
(mere) som alm. bruger. Det HAR virket!

Imidlertid er jeg blevet en smule klogere. Har f.eks. fundet ud af, at
jeg faktisk anvender udev og ikke devfs på min Gentoo. Forskellen kan
ses i det følgende, hvor jeg lige lister mit device til brænding (hdd).
Bemærk, at med udev er brugeren mig (oha), og gruppen cdrom. Jeg er
medlem af både cdrom og cdrw. Er det ikke root, der skal eje sådan et
device??

oha@linux1 oha $ id
uid=1000(oha) gid=100(users)
groups=10(wheel),18(audio),19(cdrom),27(video),35(games),80(cdrw),100(users),440(xcdwrite)

oha@linux1 oha $ ls -l /dev/hdd
brw-------  1 oha cdrom 22, 64 Feb  8  2004 /dev/hdd

Jeg har i øvrigt følgende options i min bootloader (grub):
kernel (hd0,0)/boot/bzImage-2.6.11-gentoo-r5-ide root=/dev/hda5
video=matroxfb:vesa:0x1B8 hdc=ide-cdrom hdd=ide-cdrom gentoo=nodevfs

Jeg har forsøgt både med og uden hdx=ide-cdrom. Jeg har fjernet al scsi
support i kernen (det virkede heller ikke).


Når jeg su'er til root kan jeg fint anvende xcdroast, men som brugeren
oha får jeg problemer. Når jeg under 'Setup' i fanebladdet 'Device-Scan'
højreklikker på min brænder får jeg følgende oplysninger frem med 'Show
details...'. Bemærk linje 10 for bruger, hvor der er problemer med at
allokere memory og buffer, hvorfor? Nogle gode idéer?

På forhånd tak!
Ole
