Today I notice some strange behavior of my laptop since all hotkeys did not show on-screen display anymore. All buttons still work as expect but Gnome don't get notification so mute/unmute will not effect the icon in notification area. It seems to just happer after upgrading kernel to 2.6.22-11. Well, I have found workaround.

This is my first task. I would like to run VMware under Ubuntu Gutsy Gibbon. Unfortunately, it seems like VMware doesn't support the latest kernel, 2.6.22-9, yet. As a result, I got below error messages.

Using 2.6.x kernel build system.

sudo is a must to have in all Unix host to prevent wide-spread of root account. It also has built-in security checking by time. However, sometimes this feature might annoy sudo to stop working after adjusting date/time back from the future.

sudo: timestamp too far in the future: Aug  9 18:31:44 2007

To solve this problem, I have a clue.

SAP NetWeaver is one of a cool and complete platform for large-scale enterprise backoffice. There are so many components especially in the recent version which Java development is mainstream. That's why SAP has to distribute Technology Preview to anyone interesting to learn by themselves for wide-range users, e.g., administrator, developer, manager and etc. Another benefit is to test the product world-wide as a beta test so that all testers will generate bug reports to the community.

Anyway, all previews are not the real products and there is no professional support. We have to learn how to solve issues ourselves. I just got one issue during trying test Design Time Repository for large-scale development team. The problem occurred when I tried to import development configuration in NWDS.

Import configuration failed:Could not create mountpoint for SC in compartment example.org_APPL_1: Could not create remote path /dtr/ws/Application/example.org_APPL/dev/inactive/SCs/example.org/APPL/_comp/TopLevelDCs/ (Internal Server Error).

It took me so long to setup fglrx driver for ATI Mobility X300 in my laptop, IBM Thinkpad T43. Actually, the ATI open source driver comes with Xorg 7.2 works very well except only 3D acceleration. The open source driver does not support 3D acceleration for ATI Mobility X300. As a result, Google Earth is useless because I can't even drag the earth to see my home. There are so many howto but none of them worked for me even this one. Now I found the exact problem and its solution to make fglrx 8.35.5 work perfectly on Ubuntu Feisty.

Today morning, I decided to upgrade my laptop to Ubuntu 7.04 Feisty Fawn Herd 5. Actually, Herd 5 was released a week ago. The only thing made me wait is to run vmware-player. In Ubuntu 6.10 Edgy Eft, everything has been working almost perfect for me including built-in soundcard of BenQ Joybook S52 which I had built additional package with a small patch to alsa. Anyway, I would like to try Feisty Fawn early by the way.
