Is there some other way to check/change the selected capture device? + +I wanted to reboot to the mga1 kernel to see if that would work, but that was an unproductive adventure. + +I installed the mga1 kernel which pointed /boot/initrd.img to the mga1 kernel's initrd, which was generated of course by dracut, but didn't +work, and I couldn't boot any kernel. I booted to the rescue from the installer and re-installed the mga2 kernel, which fixed the initrd +links, so then I could boot the mga2 kernel. I restored the mga1 kernel's initrd from the backups I made before the upgrade, so then I could +also boot the mga1 kernel, but when KDM came up the mouse and keyboard didn't work and hitting the power button didn't shut down, so I had to +hold the power button to kill it. So I couldn't test if it works under the mga1 kernel. Somewhere during this process, grub got messed up +too, because /boot/grub/device.map got renamed to /boot/grub/device.map.old and replaced with an empty one, so I had to fix that by hand. + +</PRE> + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="009021.html">[Mageia-discuss] audio recording (from Line In) doesn't work in Mageia 2 +</A></li> + <LI>Next message: <A HREF="009023.html">[Mageia-discuss] audio recording (from Line In) doesn't work in Mageia 2 +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#9022">[ date ]</a> + <a href="thread.html#9022">[ thread ]</a> + <a href="subject.html#9022">[ subject ]</a> + <a href="author.html#9022">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-discuss">More information about the Mageia-discuss +mailing list</a><br> +</body></html> |
