  5. how is mandrake's ATI support?

    in Laptops and Portable Devices

    Posted

    The key to ATI on Linux is do you have DRI (Direct Rendering)

     

    $glxinfo

     

    name of display: :0.0
disabling TCL support
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
  GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating,  
  GLX_EXT_import_context, GLX_SGI_make_current_read, GLX_SGIS_multisample
client glx vendor string: SGI
client glx version string: 1.2
client glx extensions:
  GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_EXT_import_context,  
  GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_MESA_allocate_memory,  
  GLX_MESA_swap_control, GLX_MESA_swap_frame_usage, GLX_OML_swap_method,  
  GLX_OML_sync_control, GLX_SGI_make_current_read, GLX_SGI_swap_control,  
  GLX_SGI_video_sync, GLX_SGIS_multisample, GLX_SGIX_fbconfig,  
  GLX_SGIX_visual_select_group
GLX extensions:
  GLX_ARB_get_proc_address, GLX_EXT_import_context, GLX_EXT_visual_info,  
  GLX_EXT_visual_rating, GLX_MESA_swap_control, GLX_MESA_swap_frame_usage,  
  GLX_SGI_video_sync
OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI Radeon 20030328 AGP 4x x86/MMX+/SSE2 NO-TCL
OpenGL version string: 1.2 Mesa 5.0.2

     

    note direct rendering yes

     

    and

     

    Mesa DRI Radeon 20030328 AGP 4x x86/MMX+/SSE2

     

    This means I have DRI and I running at its max speed (AGP4x)

     

     

    by the way jet2k5 -

     

    Right now I get about 700 FPS from glxgears.

     

    That is better than I get with DRI

     

    $glxgears

    disabling TCL support
2118 frames in 5.0 seconds = 553.600 FPS
2186 frames in 5.0 seconds = 630.200 FPS
2140 frames in 5.0 seconds = 632.000 FPS
2194 frames in 5.0 seconds = 635.800 FPS

     

    Think you said you get around 200 FPS

     

    From your PM

    702 frames in 5.0 seconds = 140.400 FPS

    880 frames in 5.0 seconds = 176.000 FPS

    1520 frames in 5.0 seconds = 304.000 FPS

    1200 frames in 5.0 seconds = 240.000 FPS

     

    You get around 700 frames but around 200FPS. but we will fix that this week. :P

     

    I will probably make a ATI Mobility How-To for DRI later (my way requires a kernel 2.6 compile)

     

     

    btw:

    If a Nvidia card tries glxinfo and getts direct rendering no Im pretty sure that means nothing. Nvidia has its own DRI. Rest assured if you glxgears is over around 400 you probably have DRI on.

  9. Savage4 PCI issue

    in Installing Mandriva

    Posted

    Crashdamage do you have DRI working also?

     

    type in a terminal

     

    $glxinfo | grep direct

     

    What do you get?

     

    I get:

    acdispatcher@arora ~ $ glxinfo | grep direct

    disabling TCL support

    direct rendering: Yes

     

    The reason I ask is because I have a Diamond Stealth 32MB PCI card and I could never get DRI to work.

  10. Schedtool

    in Virtual Machines and Emulators

    Posted · Edited by ac_dispatcher

    Additional note:

     

    This only applies if your kernel uses the staircase+sched* patches..

     

    if you get something like:

     

    ERROR: could not set PID 0 to I: SCHED_ISO - policy not implemented

     

    You dont need schedtool

     

    Edit:

    Even though I use Gentoo with the "nitro" kernel - since I found the same program for Mandy 10 I figured someone may need it.

  13. Mandrakelinux 10.1 Release Candidate 1

    in Software

    Posted

    Note to all on the 10.1 release:

     

    From The release notes:

    Switch to udev

    and

    Switch to udev, update of dynamic and the initscripts, that is

    likely to bring some fun, so test and test again.

    Ive been on udev in Gentoo for a while now. its a bit different.

     

    Kernel info:

    Kernel 2.6.8.1 breaks CD burning as a user ; again this kernel panic at the end of installation, we are working on it.

    That is standard with the 2.6.8 kernel

     

    Added New:

    The litte net applet in the task bar to check the network status

    Check it out

    http://www1.mandrakelinux.com/en/101beta.php3

     

    To answer the flood of questions: What is udev?

     

    Ripped from Gentoo docs:

    The /dev Directory

     

    When Linux-users talk about the hardware on their system in the vicinity of people who believe Linux is some sort of virus or brand of coffee, the use of "slash dev slash foo" will return a strange look for sure. But for the fortunate user (and that includes you) using /dev/hda1 is just a fast way of explaining that we are talking about the primary master IDE, first partition. Or aren't we?

     

    We all know what a device file is. Some even know why device files have special numbers when we take a closer look at them when we issue ls -l in /dev. But what we always take for granted is that the primary master IDE disk is referred to as /dev/hda. You might not see it this way, but this is a flaw by design.

     

    Think about hotpluggable devices like USB, IEEE1394, hot-swappable PCI, ... What is the first device? And for how long? What will the other devices be named when the first one disappears? How will that affect ongoing transactions? Wouldn't it be fun that a printing job is suddenly moved from your supernew laserprinter to your almost-dead matrix printer because your mom decided to pull the plug of the inkjet which happened to be the first printer?

     

    Enter udev. The goals of the udev project are both interesting and needed:

     

        * Runs in userspace

        * Dynamically creates/removes device files

        * Provides consistent naming

        * Provides a user-space API

     

    To provide these features, udev is developed in three separate projects: namedev, libsysfs and, of course, udev.

    You can write your own udev rules! What that does is identify a spicific device and load it into the /dev directory as a link you name. Example:

     

    I have an RF cordless usb mouse. I wrote a udev rule so that when that extact mouse is plugged in it is linked to /dev/rodent.

  14. Schedtool

    in Virtual Machines and Emulators

    Posted

    I recently found out that the kernel I use (nitro) has a patch that makes games in cedega choppy. I found a cool program to fix the error-

     

    its called schedtool and it works like this:

     

    $schedtool -I -e cedega game.exe

     

    I have tried useing the "nice" cmmand in the past with little help but schedtool works great.

     

    Via google I found Mandy has it too

    Try it out

  23. Have you ever been compromised?

    in Security

    Posted · Edited by ac_dispatcher

    I'm trying to see how everyone has there setup and if they have been compromised ever. Maybe have some tips or tricks posted on catching and stopping it.

     

    No I don't think I've been rooted but for that matter I feel I've been a bit lax or lazy on security lately.

     

    Im not as secure as I should be but Im probably better than others. Here is my set up:

     

    My house is hard wired with Cat 5E to a Hub (only 10baseT)

    The hub is located in my Coyote Linux firewall box.

     

    Wired Set up of my house:

     

    INTERNET

    >

    >

    Coyote Linux

    >

    >

    10BaseT Hub

    >

    >

    > > >Windows XP (nuclear)

    >

    > > > Windows XP (tiger) >>> Bridge >>> Gentoo Laptop (arora)

    >

    > > > Windows98 (vectra)

    >

    > > > Windows98 (elite)

     

     

    Ok thats my basic setup. I put each computer name beside each to easier identify them. I run a network bridge (2 Nics) on (tiger) for two reasons: 1. the HUB only has 4 ports, 2 - So it has a 10/100 connection from arora to tiger for rsync backups. Now I know that its not to good of a setup. I need to do more about security.

     

    Security:

    Coyote Linux Box:

    First and last wall of defense for me. Its a computer that runs Coyote Linux via a floppy. No hard drive just a P75Mhz, 12Mb Ram, and 2 Nics. Write protect the floppy and If I think I've been compromised I just reboot the box and change the password. I have ran port scans via GRC, Sygate scan, DSL reports, with full stealth. I have it set for no outside logins allowed. Good password used for root. No additional logins made.

     

    I have remote logging to my Gentoo box enabled and check the logs at least twice a week (usually via grep)

     

    All other boxes:

    Wide open no firewall or security measures. No passwords.

     

     

    Why ? Half lazy half easy of use. I know that its not the best but I tend to think the WindowsXP user with his new Cable connection and no firewall has more to worry about.

     

    Additional Info:

     

    I share folders from each computer to my Gentoo box via samba.

     

    I run VNC from/to all computers

     

    Each Windows XP box has a spyware and Anti virus software installed and up to date. Norton/ McAfee and Spybot/Webroot. I have different programs on each so I don't have all my eggs in one basket. Each box runs a virus scan on all drives over my entire network each night (takes about 3 hours). So the entire network is scanned via two different Antivirus programs each night.

     

    My wifes computer (nuclear) is her work computer. I also block all outbound ports via coyote to the internet except a few choice ones (web, smtp, pop). So if she gets compromised or tricked into installing maleware her computer is blocked on the outbound.

     

    >>>>>

    Things I plan to do:

     

    vectra - needs no outside access so I plan on blocking all outbound (internet) via the firewall

     

    elite - This is my 7 year olds computer so I plan on blocking every outbound port except port 80 via the firewall.

     

     

    Im thinking its time to tighten up all the computers behind the firewall. I thinking of downloading Zonealarm and installing it on all Window$ boxes. I have experience with it and how to set it to allow access. I stopped a while ago because I have trouble with Zonealarm and VNC, but Im going to try and give it a go again.

     

     

    So how about some Links huh?

    So what is this thread about?

     

    1. What kind of setup do you have?

    2. Have you ever been compromised?

    3. Do you have any tips/tricks?

    4. Any Home Networking Advice (Hardware or Software)

     

     

    What spawned this thread? I read this on the Gentoo Forum -

    Remember years ago when a Anti Virus program was recommended? :P
