openSuse 12.2 RC2 Impressions, wating for 12.2 RTM

I got openSUSE 12.2 at college, and split them up in 200 MB 7z archives for my thumb drive. It comes with KDE 4.8.2, Gnome 3.4.1 XFCE 4.9 and kernel 3.4.6-1. I've only installed 3.3 on my laptop(s).

KDE 4.8 is a little less buggy than KDE 4.7.2 in openSuse 12.1. KDE applications released today include Dolphin with its new display engine, new Kate features and improvements, Gwenview with functional and visual improvements. KSecretService is a new framework for sharing saved passwords and other credentials between a wider range of applications. KDE Telepathy —the new real-time communication and collaboration framework for KDE Workspaces with Speex VoIP for other Linux users. Why not use Google talk instead? Google Talk would get integrated with Google+. There is no "KDE+". Plasma Components offer an efficient, elegant and powerful set of widgets, which integrate well with the underlying platform. Combined with Plasma's visual and data integration components, application development has never been easier, more fun and powerful. Plasma Components automatically adapt to the device they are used on, making it easy to share code between Desktop and mobile and touch-based applications and allowing deployment and usability on a wider range of target devices.

Unfortunately, OpenSuse 12.2 didn't go with MATE 1.2, an enhancement of Gnome 2 nor did it go with Cinnamon 1.4, enhancement of Gnome 3.x. Gnome 3.4.x new feature is the Network password dialogs, including those for VPN passwords, present in Gnome 2.x. Our built in screen recorder now produces smoother videos while also using less system resources. To use it, simply press Control+Shift+Alt+R using Ogg Theora.

    Gnome 3.4 has improved network panel layout, which now allows you to forget the configuration of individual networks.  A better looking power panel, which includes a redesigned status section. Greatly enhanced Wacom graphics tablet support, including calibration and button mapping, as well as the new ability to configure multiple tablets. Easier navigation thanks to the renaming of some panels and an updated 'All Settings' button. This provides a really nice way to do video calling (Ogg Theora) , and it is fully integrated into GNOME 3. System Monitor has received Control Groups support.

Kernel 3.4 has graphics support for the GeForce GTX 680 and Radeon HD 68xx. Xen Hypervisor to adjust the processor speed or send the CPU into a short-term sleep state when using Linux 3.4 on the Dom0.he MD software RAID code can now resize RAID 10 arrays in such a way that, for example, extra space in component devices can be used after the underlying disks have been exchanged for larger ones.As usual, there are a number of improvements to the drivers and infrastructure for DVB hardware, including support for the KWorld PC150-U ATSC hybrid tuner card, as well as for the AzureWave 6007 and related USB 2.0 DVB-T/C hardware. A new Realtek RTL2831U driver for DVB-T hardware has also been added. The Brcmfmac Broadcom WLAN driver now works with the Bcm43235/6/8 USB chips, while the rt2x00 Ralink driver, starting with 3.4, supports the RT5372 WLAN chipset. The rtl8187 driver, responsible for the Realtek chip with the same name, now provides ad hoc support. OpenSuse 12.2 also provides basic support for ACPI 5.0.The Ext4 code gained a new mechanism for resizing Ext4 filesystems. The new mechanism needs only 3.5 seconds to resize a 20 GB drive to 230 GB. The MD code responsible for software RAIDs gained functions (for example 1, 2) to copy data currently on one storage device to another so that the first can later be removed. This "hot replace" reduces the danger of losing data when changing disks that are part of the RAID, since it avoids the rebuild (which creates a new version of the redundant data on the new data volume) that has previously been necessary for such an exchange. A rebuild is not without its risks, since the data has to be read from the remaining data volumes, which could have developed corrupt areas; in addition, except for a RAID 6, there is no redundancy during a rebuild. The kernel is able to perform a "hot replace" for RAID levels 1, 4, 5, 6, and 10. The DRM/KMS driver for Intel GPUs will enable the very efficient and Intel-specific RC6 graphics power-saving feature by default. The kernel developers have extended the TCP stack of Linux 3.2 to provide "Proportional Rate Reduction" (PRR) support. The Ext4 filesystem now supports big allocation blocks. The technique, known as bigalloc, bundles the 4K blocks used to store data into clusters of up to 1 MB. This reduces administrative overhead when saving large files and should significantly improve performance in some scenarios. With the help of the new CFS bandwidth controller and the control groups (cgroups) infrastructure, it is now possible to cap process group CPU time. One use case of this is to permit cloud operators to ensure that users are not able to consume more CPU resources than they have paid for. I don't get any FFMPEG decoders or VLC 2.x like Linux Mint 13 which is obviously GPLed. What is wrong with these Linux developers?
