Re: [Flightgear-devel] Rembrandt - ATI Radeo HD 2600 XT - Ubuntu 10.04
Never heard of such, buy anyway I never update, but do a reinstall. Hence back up your 10.04 data, then from the vista cd do a fixmbr or alike. Search the exact syntax. update vista and simply reinstall 12.04 after reformating with ext4. And yes let me know how it goes. I wanted to install sp2 in vista but couldn't.- It rolled back update after 2 hours or so...sigh.

[Flightgear-devel] Hard-coded movement for Nasal-generated models
I would like to point the attention of people who can commit on flightgear and simgear to two merge requests put in by Vivian recently: https://www.gitorious.org/fg/simgear/merge_requests/26 https://www.gitorious.org/fg/flightgear/merge_requests/1564 This contains functionality which is relevant for Advanced Weather, and it would be very good to have this in before feature freeze. The context is as follows: When I restructured the Advanced Weather code to remove stutter, I (knowingly) introduced a bug by removing the Nasal-generated motion of 2d Cirrus clouds and rain layers. The need to move 2d clouds around was a large chunk of what caused uneven framerate, and I eliminated the Nasal code for movement since the benefits in terms of smooth framerate outweigh the potential problem. That problem is that 3d clouds are done by a different rendering technique than the 2d Cirrus cloud models or the rain layers. All 3d clouds move with the wind, and if we have no way of moving 2d clouds and rain layers, they'd stay behind. For instance, in a storm, you'd see the cloud front approaching but the rain front would simply be left behind disconnected from clouds. Similarly, I sometimes do ridge-riding with a glider where the winds are quite strong but I stay basically in the same location. In this case, you see the weather drifting over you and new tiles are essentially generated because the tile coordinate reference moves, not because the aircraft position moves. If Cirrus clouds would not move, they'd all pile up in the same location in the sky as new tiles are generated, creating very ugly artefacts. In many situations though you wouldn't see the lack of movement of some objects (i.e. if winds are weak or if no 2d Cirrus or rain layers are in the scene), so the bug is not immediately crippling. The curse of weather modelling is - once you move anything with the wind, you have to move everything or you create artefacts. As I've learned, it's much easier never to move anything around, and from an airliner, you never even see the difference. But it wouldn't do to drift with an airship through static clouds... The patches are an attempt to provide a hard-coded (and garbage-collector-save) means to move a limited number of Cirrus clouds and Rain layers. I have a matching bugfix ready for Advanced Weather and I have tested the patches and the bugfix for the last few days, so far I have not observed any problem which I could relate to the patches. I would therefore ask that the patches are committed to have a 2.8 without the unmoving rain bug.

Hi Fred, Glad to hear the HD 7750 works fine in Win 7 64-bits... it seems very similar to the HD 7770 so no idea why I have such a bad 'crash' with Rembrandt ;=() Maybe later driver updates, or even as Rembrandt matures... I can only hope ;=)) will keep trying now and again, but the completely black screen for several seconds is quite frightening... Hi Björn, Try this - http://apcmag.com/vista_sp1_wont_install_on_dualboot_systems_microsoft.htm And just search 'vista sp1 and grub' for MANY others ;=(( And with no SP1 many other vista updates also FAIL! And a suggested solution NOT tried - https://blogs.oracle.com/pomah/entry/installing_windows_vista_service_pack and have read others in similar vane - remove grub, do update, restore grub (if you are lucky!). I am certainly GLAD to hear you had no similar problem with Windows 7 ;=)) After the above Vista fiasco I am sure MS would want to avoid that happening again - we hope!!! Hi Michael, Yes, a save, and removal of 10.04, get Vista back into shape, and re-install 12.04 LTS is certainly another option... ;=)) But my $HOME directory is a whopping 80-100 GB! But I think I remember moving that to another logical drive so maybe it would not get wiped in a reformat of the 'system' drive... need to check... But as stated, that is for July anyway... when I feel 12.04 LTS is 'solid' ;=)) Regards, Geoff. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Hey Geoff, sad to see that it's a common problem. But then again, Vista generally wasn't one of MS's better products...

[Flightgear-devel] NVRM warnings and freeze issues since FG 2.6 on a GTX 260
Hello! I decided to write here too in case someone else has experienced this issue. In specific, I have a Gentoo box dedicated to music production, 3D modelling and Flightgear, aiding me with my pilot studies. (Specs: Motherboard: Gigabyte EX58-UD5 F12, CPU: i7 920@2.80 GHz Quad core, Memory: 12Gb RAM, GFXCard: Gigabyte GeForce GTX 260 896Mb, OS: Gentoo Linux x86_64FG: current Git) I've been having these issues with Flightgear Git (started with 2.6), the sim and the entire system (except sound!!) freezing for 10-15 secs, from every 2 to 10 mins. Dmesg reports:[ 140.311822] NVRM: Xid (:02:00): 8, Channel 0003[ 142.309503] NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt context So far I've tried:Contacted the Nvidia team through the Nvnews forum (thread with my logs and feedback here: http://www.nvnews.net/vbulletin/showthread.php?t=177732 )Built 4 different kernels, from 2.6.25, to 3.2.1, to 3.2.17-rt (!!), to 3.4.2 Tried these kernels with stable and unstable drivers since September up to date.Tried Unigine benchmarks in different setups, which ran with no problems or freeze-ups. Now, I know that so far it seems kind of off-topic for this list, however there are some points I would like to bring up which could (although I seriously doubt it) be because of the sim or even OSG. These are:The bug/freeze does not occur if I just stay on the starting point (rwy or parking). (No texture loading...???!)The bug/freeze does not occur if I fly over sea. (RMK: The console log was complaining about some .DDS sea-related textures not being decompressed which could affect stability. I loaded and saved them with GIMP, and now there is no warning. It could have affected over-sea flying stability)2-3 months ago using the then latest driver I was able to sink the 3D cloud distance at 25000m to prevent from having these freeze-ups. However, it does not seem to be reproducible now...Flightgear is the only program this freeze-up happens (with the exception of Blender, 2-3 months ago. Does not happen now, as far as I have checked) My apologies for taking your time. If there is any more info (logs, etc) you would wish for me to provide, just let me know.

[Flightgear-devel] Slow frame rates, --model-hz effect
Some years ago when I started flying FlightGear 2.0, I added --model-hz=480 to my startup aliases for reasons I no longer remember. I've continued to use these aliases through 2.4 and 2.6 with no real ill effect. However, on a git build from June 13 I've noticed that using them really clobbers the framerate. Instead of getting 30 - 50 fps without this argument, I get more like 1-2 fps with it set. These frame rates are based on a default configuration, with the .fgfs directory erased immediately before starting. I'm not sure if this is a bug or just a change in the way that this flag functions, but at the very least we should note in the documentation that this command-line argument can create problems with 2.7. Even without this flag set, I'm getting extremely low frame rates of 1 - 4 fps on at least some aircraft (e.g., the Trimotor) until the aircraft breaks ground, then it suddenly jumps to 30+ fps. Landing and taking off again retains the 30+ fps frame rate. 8-core AMD machine, 8 G RAM, nVidia GTX 560, running Kubuntu Maverick.

[Flightgear-devel] Slow frame rates
Additional finding: if you do a File -- Reset immediately after startup, the slow 1 - 2 fps problem goes away immediately and frame rates stay high thereafter. Something seems to be getting initialized either when breaking ground during takeoff or in a File -- Reset that is not getting initialized on initial startup.
