Hello Can you provide more info about your PC? And one more..why don't you install the 8.04 version? It owns a newer kernel, and better hardware support. Maybe that would work flawlessly. I think it worth a try.. (Few other user said the same on this version, but only on notebooks mainly and the updates / 8.04 upgrade fixed the problem, so I don't know a full workaround). (You can upgrade your system by the tray applet, or just open a konsole, and type: sudo aptitude update && sudo aptitude full-upgrade) Asuka <div class="gmail_quote">2008/5/4 Esterhuizen, Roy (Suncoast) <<a href="mailto:roye@tsogosun.com">roye@tsogosun.com</a>>: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div link="blue" vlink="purple" lang="EN-US"> <div> Hi, today I installed kubuntu 7.10 on my pc, I am still pretty new to this stuff. Everything seems to be working great, even got my Huewai E220 hsdpa modem working, but for some reason when ever I log off my pc, not shutdown, just logoff my user to allow another user to login, the pc freezes, and I get a black screen with a couple of blocks, I then need to reboot the computer physically. Has anyone had this problem and does anyone know how to fix it? </div> </div> -- kubuntu-users mailing list <a href="mailto:kubuntu-users@lists.ubuntu.com">kubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/kubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/kubuntu-users</a> </blockquote></div>
