  • Could not apply stored configuration for monitors

    - by Hernantz
    Well this happened when I upgraded to Natty. Not only seems I can't change my resolution to higher than 1024x768 but it appears at the left and using only 70% of the monitor's width. I tried logging in but in ubuntu classic mode, and i was able to change it, but that trick did not work anymore. (May this be a compiz problem?) Anyways, here is my /var/log/Xorg.0.log http://pastebin.com/Ew4wwLab and lspci -nn | grep VGA: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03) I tried using xrandr for adding manually a resolution of 1280x1768 but without luck.

  • Atheros Wireless card shows up as two different models?

    - by geermc4
    Hi I've been fighting these wireless drivers for a few days and just recently i noticed that the model the Wireless controller appears in lspci is different sometimes. This is the data i have after installing Ubuntu Server 64 bit ~# lspci -k .... 04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Subsystem: AzureWave Device 1d89 Kernel driver in use: ath9k Kernel modules: ath9k ran some updates, restarted, all was good, all though it did say that linux-headers-server linux-image-server linux-server where beeing kept back. After that i installed ubuntu-desktop (aptitude install ubuntu-desktop --without-recommends) restarted and not only is the wireless not working anymore, but the hardware is listed as a different card ~# lspci -k .... 04:00.0 Ethernet controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01) has no available drivers for it, still i tried to modprobe ath9k, they show up in lsmod as loaded, but still iw list shows nothing. this is what it looked like before the ubuntu-desktop instalation Wiphy phy0 Band 1: Capabilities: 0x11ce HT20/HT40 SM Power Save disabled RX HT40 SGI TX STBC RX STBC 1-stream Max AMSDU length: 3839 bytes DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 8 usec (0x06) HT TX/RX MCS rate indexes supported: 0-7 Frequencies: * 2412 MHz [1] (14.0 dBm) * 2417 MHz [2] (15.0 dBm) * 2422 MHz [3] (15.0 dBm) * 2427 MHz [4] (15.0 dBm) * 2432 MHz [5] (15.0 dBm) * 2437 MHz [6] (15.0 dBm) * 2442 MHz [7] (15.0 dBm) * 2447 MHz [8] (15.0 dBm) * 2452 MHz [9] (15.0 dBm) * 2457 MHz [10] (15.0 dBm) * 2462 MHz [11] (15.0 dBm) * 2467 MHz [12] (15.0 dBm) (passive scanning) * 2472 MHz [13] (14.0 dBm) (passive scanning) * 2484 MHz [14] (17.0 dBm) (passive scanning) Bitrates (non-HT): * 1.0 Mbps * 2.0 Mbps (short preamble supported) * 5.5 Mbps (short preamble supported) * 11.0 Mbps (short preamble supported) * 6.0 Mbps * 9.0 Mbps * 12.0 Mbps * 18.0 Mbps * 24.0 Mbps * 36.0 Mbps * 48.0 Mbps * 54.0 Mbps max # scan SSIDs: 4 max scan IEs length: 2257 bytes Coverage class: 0 (up to 0m) Supported Ciphers: * WEP40 (00-0f-ac:1) * WEP104 (00-0f-ac:5) * TKIP (00-0f-ac:2) * CCMP (00-0f-ac:4) * CMAC (00-0f-ac:6) Available Antennas: TX 0x1 RX 0x3 Configured Antennas: TX 0x1 RX 0x3 Supported interface modes: * IBSS * managed * AP * AP/VLAN * WDS * monitor * mesh point * P2P-client * P2P-GO software interface modes (can always be added): * AP/VLAN * monitor interface combinations are not supported Supported commands: * new_interface * set_interface * new_key * new_beacon * new_station * new_mpath * set_mesh_params * set_bss * authenticate * associate * deauthenticate * disassociate * join_ibss * join_mesh * remain_on_channel * set_tx_bitrate_mask * action * frame_wait_cancel * set_wiphy_netns * set_channel * set_wds_peer * connect * disconnect Supported TX frame types: * IBSS: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * managed: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * AP: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * AP/VLAN: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * mesh point: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * P2P-client: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 * P2P-GO: 0x0000 0x0010 0x0020 0x0030 0x0040 0x0050 0x0060 0x0070 0x0080 0x0090 0x00a0 0x00b0 0x00c0 0x00d0 0x00e0 0x00f0 Supported RX frame types: * IBSS: 0x00d0 * managed: 0x0040 0x00d0 * AP: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 * AP/VLAN: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 * mesh point: 0x00b0 0x00c0 0x00d0 * P2P-client: 0x0040 0x00d0 * P2P-GO: 0x0000 0x0020 0x0040 0x00a0 0x00b0 0x00c0 0x00d0 Device supports RSN-IBSS.

  • C-states and P-states : confounding factors for benchmarking

    - by Dave
    I was recently looking into a performance issue in the java.util.concurrent (JUC) fork-join pool framework related to particularly long latencies when trying to wake (unpark) threads in the pool. Eventually I tracked the issue down to the power & scaling governor and idle-state policies on x86. Briefly, P-states refer to the set of clock rates (speeds) at which a processor can run. C-states reflect the possible idle states. The deeper the C-state (higher numerical values) the less power the processor will draw, but the longer it takes the processor to respond and exit that sleep state on the next idle to non-idle transition. In some cases the latency can be worse than 100 microseconds. C0 is normal execution state, and P0 is "full speed" with higher Pn values reflecting reduced clock rates. C-states are P-states are orthogonal, although P-states only have meaning at C0. You could also think of the states as occupying a spectrum as follows : P0, P1, P2, Pn, C1, C2, ... Cn, where all the P-states are at C0. Our fork-join framework was calling unpark() to wake a thread from the pool, and that thread was being dispatched onto a processor at deep C-state, so we were observing rather impressive latencies between the time of the unpark and the time the thread actually resumed and was able to accept work. (I originally thought we were seeing situations where the wakee was preempting the waker, but that wasn't the case. I'll save that topic for a future blog entry). It's also worth pointing out that higher P-state values draw less power and there's usually some latency in ramping up the clock (P-states) in response to offered load. The issue of C-states and P-states isn't new and has been described at length elsewhere, but it may be new to Java programmers, adding a new confounding factor to benchmarking methodologies and procedures. To get stable results I'd recommend running at C0 and P0, particularly for server-side applications. As appropriate, disabling "turbo" mode may also be prudent. But it also makes sense to run with the system defaults to understand if your application exhibits any performance sensitivity to power management policies. The operating system power management sub-system typically control the P-state and C-states based on current and recent load. The scaling governor manages P-states. Operating systems often use adaptive policies that try to avoid deep C-states for some period if recent deep idle episodes proved to be very short and futile. This helps make the system more responsive under bursty or otherwise irregular load. But it also means the system is stateful and exhibits a memory effect, which can further complicate benchmarking. Forcing C0 + P0 should avoid this issue.

  • Symbol of VPNanytime is not shown anymore after upgrading from Ubuntu 11.04 to 11.10

    - by Aufwind
    Usually when I start VPN anytime (by calling a certain url in firefox) in Ubuntu 11.10 I saw a little "green symbol with a yellow lock in front of it" for the VPN anytime client near the clock. If I wanted to quit the VPN connection I just clicked on this symbol and hit logout/quit. Today I upgraded to Ubuntu 11.10 and the VPN connection works here fine too. But the symbol near the clock is not shown anymore. Is this a bug or do I have to set this up manually? And is there a way to quit the client perhaps by terminal? Currently I just do a restart, when I want the vpn connection terminated and that's kind uncomfortable. :-) Thanks for any suggestions!

  • How to make Devilspie Make an Applet be "silent" but then openable

    - by Kendor
    Am using gnome-shell with 11.10. I have two panel based applets (Toggl and Gnome Alarm Clock) that I run at startup. The issue is that they start as Windows, and I'd like them to start "silently" but still be able to recall their interface when I need them. I installed Devilspie and gDevilspie which properly "close" the applets after starting them, but there's a "Catch 22." Because of the "close" behavior, they can never be opened again as long as the Devilspie daemon is running.. Is there a way around this? An example of the rule I'm using is this: ( if ( begin ( is ( application_name ) "alarm-clock-applet" ) ) ( begin ( close ) ( println "match" ) ) )

  • Which DB should I use for my newbie program?

    - by knijo
    I'm really new to programming, and I need some advice. I'm currently working on a very simple program to maintain a list of users at a company, as well as their clock in and clock out info. I would like to make this application easy to distribute (on a cd probably), and I'm looking for advice on which database to use for storing my data. My application is implemented using java and swing. A friend recommended MySQL, but I don't want to go installing the db server on every computer the application is installed on. Another friend recommended Access. Any tips would be greatly appreciated

  • Bomb timer adventure game win32 c++ [on hold]

    - by user3491746
    I'm working on an adventure game in win32 and opengl for my 2nd year university project for class. I am pretty much finished my game but I'm stuck on the concept of how to program a timer which outputs hh : mm : ss -- but which countdown, not up. I've made a clock which counts up using vector matrices and the segxseg matrix algorithm but I cannot figure out how to make a clock (it can be simple even text using wsprintf) that counts down in that format. Can anyone possible give me an example or some literature that I can read on how to do this? Please dont suggest for me to use another environment, I've already been working here for 2 months on this game, and I'm pretty much done so i'm at no point to switch over. Can anyone show me how I can take a shot at this component of my project? Thanks a bunch! Anything that I can get is appreciated.

  • Why is the superblock last mount time in the future?

    Future time: Since installing Ubuntu 12.04, I regularly have to fun fsck and reset my clock because it shows a 'future time' : Err.Msg. "superblock last mount time is in the future by less than a day, probably due to hardware clock being incorrectly set." FIXED. According to what I have read, it looks like I'm in the right place to get an answer. Following are my feeble attempts to rectify this annoyance: mjh@mjh-desktop:~$ sudo service ntp start [sudo] password for mjh: ntp: unrecognized service mjh@mjh-desktop:~$ mjh@mjh-desktop:~$ sudo apt-get install update Reading package lists...

  • HW resources for the device driver [closed]

    - by VladimirLenin
    Need to provide memory and IRQ resources to the Linux kernel in order to bring up the CAN controller. Have no idea how to get them. Below is the structure I need to fill in. This structure I have taken for example, this is for the Run-Time Clock, but I need for CAN controller. Both are on the same board, and there are constants for RT Clock (and all other devices), but not for my CAN chip. When looking at the subject chip driver's code (sp_probe() function), I see it needs the same type resources. struct resource tegra_rtc_resources[] = { [0] = { .start = ???, .end = ???, .flags = IORESOURCE_MEM, }, [1] = { .start = ???, .end = ???, .flags = IORESOURCE_IRQ, }, };

  • Distorted choppy audio in Precise

    - by Misery
    After installing Precise on my PC, some problems with soud occure. While using Lucid there were no problems. The sound is choppy and distorted in low tones range. As I absolutely have no experience in setting/testing and doing anything with Audo Devices I need help even to diagnose the problem. update: sudo lshw -c multimedia *-multimedia description: Audio device product: Radeon X1200 Series Audio Controller vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 5.2 bus info: pci@0000:01:05.2 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi bus_master cap_list configuration: driver=snd_hda_intel latency=32 resources: irq:19 memory:fdafc000-fdafffff *-multimedia description: Audio device product: SBx00 Azalia (Intel HDA) vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 14.2 bus info: pci@0000:00:14.2 version: 00 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: driver=snd_hda_intel latency=32 resources: irq:16 memory:fe024000-fe027fff update 2: It has something to do with the volume.

  • What is the point in using real time?

    - by bobobobo
    I understand that using real time frame elapses (which should vary between 16-17ms on average) are provided by a lot of frameworks. GetTimeElapsedSinceLastFrame, and it gives you the wall clock time. But should we use this information in basic physics simulation? It looks to me to be a bad idea. Say there is a slight lag on the machine, for whatever reason (say a virus scanner starts up). The calculations all jump, and there is no need for this. Why not use a virtual second and ignore wall clock time? For gameplay on the level of Commander Keen, shouldn't you always use the virtual second and not real-time? (Besides stopwatch timing for race games) I don't see a need to use real time and not a fixed 16ms time step.

  • Check if the vector is behind another or maybe opposite directions?

    - by Gilson
    I'm doing a network game and on the client side, i interpolate the client position with the server sent extrapolated position. The client has its own physics simulation wich is corrected by the server in steps. The problem is when it laggs and i 'kick' the ball, the server gets a delayed message and sends me the position backwards of the client position wich makes the ball goes back and forth. I want to ignore those and maybe compensate that on the server, not sure though. The problem is the clock difference on those case are 0.07ms or 0.10 ms wich isn't that high to ignore the message i guess. When i get the server position, i extrapolate with the clock interval * serverBallVelocity Can i check if my new ball server position is behind my actual ball vector position? I tried to use the dot product after normalized the two vectors to check if they are opposite but it ain't working properly. Any suggestions on checking that?

  • How to synchronize the ball in a network pong game?

    - by Thaars
    I’m developing a multiplayer network pong game, my first game ever. The current state is, I’ve running the physic engine with the same configurations on the server and the clients. The own paddle movement is predicted and get just confirmed by the authoritative server. Is a difference detected between them, I correct the position at the client by interpolation. The opponent paddle is also interpolated 200ms to 100ms in the past, because the server is broadcasting snapshots every 100ms to each client. So far it works very well, but now I have to simulate the ball and have a problem to understanding the procedure. I’ve read Valve’s (and many other) articles about fast-paced multiplayer several times and understood their approach. Maybe I can compare my ball with their bullets, but their advantage is, the bullets are not visible. When I have to display the ball, and see my paddle in the present, the opponent in the past and the server is somewhere between it, how can I synchronize the ball over all instances and ensure, that it got ever hit by the paddle even if the paddle is fast moving? Currently my ball’s position is simply set by a server update, so it can happen, that the ball bounces back, even if the paddle is some pixel away (because of a delayed server position). Until now I’ve got no synced clock over all instances. I’m sending a client step index with each update to the server. If the server did his job, he sends the snapshot with the last step index of each client back to the clients. Now I’m looking for the stored position at the returned step index and compare them. Do I need a common clock to sync the ball? EDIT: I've tried to sync a common clock for the server and all clients with a timestamp. But I think it's better to use an own stepping instead of a timestamp (so I don't need to calculate with the ping and so on - and the timestamp will never be exact). The physics are running 60 times per second and now I use this for keeping them synchronized. Is that a good way? When the ball gets calculated by each client, the angle after bouncing can differ because of the different position of the paddles (the opponent is 200ms in the past). When the server is sending his ball position, velocity and angle (because he knows the position of each paddle and is authoritative), the ball could be in a very different position because of the different angles after bouncing (because the clients receive the server data after 100ms). How is it possible to interpolate such a huge difference? I posted this question some days ago at stackoverflow, but got no answer yet. Maybe this is the better place for this question.

  • Html 5 &ndash; new size units

    - by Norgean
    There are some new size units with CSS 3, which allows you to resize elements relative to the viewport size. They are vw, vh, vmin (that’s vm in IE), and perhaps vmax. (Viewport width, height, smaller of the two, larger of the two.) 8vw is 8% of the viewport width – or 205 pixels on my 2560 screen. I created a tiny demo clock which sizes the elements so that it uses the whole screen. Clock – in Norwegian, but it’s the source that is interesting… Bug: Resize does not work. Tested for IE 9 & 10 and Chrome. Firefox and Safari: does not work.
