Karmic Target Versions for Release ---------------------------------- kernel: 2.6.31 libdrm: 2.6.12 mesa: 7.6 x-server: 1.7 (Brings libxi 2.0, inputproto 2.0, evdev 2.3) xorg: 7.5 (We are carrying rc versions of the above currently, but anticipate these versions will be released in time for Karmic.) UPDATE - As of Alpha-4, some components were unavailable. We are now targeting the following: kernel: 2.6.31 libdrm: 2.6.12 mesa: 7.6 x-server: 1.6.3 xorg: 7.4 Karmic Important Dates ---------------------- June 19th xserver 126.96.36.1991 + xorg 7.5 beta 1 July 15th xserver 1.7 + xorg 7.5 release Sept 7th Ubuntu Deadline for driver version updates Oct 1st Ubuntu Beta Oct 29th Ubuntu Final Release Driver-Specific Requirements ---------------------------- -intel: All Intel chipsets >= i810 Version: 2.8 (potentially 2.9 if schedule permits) AccelMethod: UXA DRI: DRI2 Memory: GEM KMS: "On" for all chipsets by default Duallink DVI: Chipsets >= i830 TV-Out: Chipsets >= i830 DisplayPort: Best efforts (G40-series) -ati: All Radeon chipsets Version: Unspecified AccelMethod: EXA DRI: 3D on chipsets R5xx and older only Best efforts for newer chipsets Memory: Unspecified KMS: "On" for chipsets R5xx and older only Best efforts for newer chipsets Duallink DVI: R400 and newer TV-Out: R1xx-R3xx DisplayPort: No -fglrx: Radeon chipsets R600 and newer only Version: 9.10 AccelMethod: Unspecified DRI: Unspecified Memory: Unspecified KMS: No Duallink DVI: R600 and newer TV-Out: R600 and newer DisplayPort: DCE 3.0 chipsets and newer -nouveau: All Nvidia chipsets >= NV04 Version: Unspecified AccelMethod: EXA DRI: 2D only Best efforts for 3D Memory: Unspecified KMS: "On" for NV40 and newer Best efforts for older chipsets Duallink DVI: Unspecified TV-Out: Unspecified DisplayPort: G98 only -nvidia (legacy): Older Nvidia chipsets Version: -96.x, -173.x AccelMethod: Unspecified DRI: Unspecified Memory: Unspecified KMS: No Duallink DVI: Unspecified TV-Out: Unspecified DisplayPort: No -nvidia (current): GeForce 6xxx and newer Version: -185.x AccelMethod: Unspecified DRI: Unspecified Memory: Unspecified KMS: No Duallink DVI: Unspecified TV-Out: Yes DisplayPort: Yes Key Karmic Goals for X.org -------------------------- 1. KMS / Flicker-Free Boot Kernel mode-setting (KMS) is a major target objective for this release. We may be updating to newer versions of mesa if needed for KMS support. We anticipate that not all drivers will support KMS, so the kernel will be determining whether to use KMS or not on a per-driver basis, and if KMS is not in use, will boot similar to how it's been done up to now. 2. Fast Boot / Fast Resume Improving boot and suspend/resume speed is another major goal for Karmic. Our objective is to boot fast enough that no splash screen is required. Therefore we will not be integrating plymouth into our boot process. Where boot speeds cannot be sufficiently reduced we will continue to use usplash. We anticipate KMS will help in achieving this objective, and are looking for additional ideas for improving X.org boot speed further. Key design points for this objective: * No plymouth at all. * No usplash for a default boot. * usplash will be started for fsck, and for entering a passphrase for encrypted root partitions. * X will be started as early as possible in the boot process and just display a bg image with a throbber. Once enough of the system is up, gdm starts and replaces the throbber. 3. Virtual Terminals In Karmic, VT1 will be used for X, VT2 as a console login, and VT3 for kernel log messages.

Design / Rationale
-intel version 2.9 may be available in time for Karmic. There are no major features planned for that release; mostly it will be removing non-KMS code (not something we care about). However it may contain some worthwhile bug fixes, so may be worth consideration if it is released with sufficient time for integration; we'll plan on 2.8 for now and see how things go.
- (DONE) Write roadmap
- (DONE) Send roadmap to video driver partners, Mobile team, and any other X.org requirements consumers
- (DONE) Pull intel-gpu-tools into Karmic/Universe
(DONE) Update directions at https://launchpad.net/~ubuntu-x-swat/+archive/x-freeze-test (Probably move into wiki)
- (DONE) Follow up with jbarnes regarding automatic GPU lockup resetting / apport triggering
- (DONE) Ogasawara says she can obtain a listing indicating the most common video hardware; this needs following up on
- (DONE) Provide jbarnes with a listing of the hardware Canonical certifies against
BoF agenda and discussion
<ghexsel> - According to Phoronix (http://www.phoronix.com/scan.php?page=news_item&px=NzI4OQ). the schedule slipped. Will it still make the cut? <bryce> - presumably yes; if not we'll ship whatever -rc version is available at the time, and backport fixes as appropriate.
