I will see if I can do that. The first kernel version which worked correctly on this laptop (including other issues I reported) was Linux version 2.6.37-trunk-amd64 (Debian 2.6.37-1~experimental.1) ([email protected]) (gcc version 4.4.5 (Debian 4.4.5-10) ) #1 SMP Thu Jan 6 14:13:28 UTC 2011 Cheers, -- Bill. <[email protected]> Imagine a large red swirl here. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
