4 UST-IP USER MANUALLinux SettingsOn target servers running Linux graphical interfaces, set the mouse acceleration to exactly 1 and setthreshold to exactly 1.As mentioned above, please ensure that each target server running Linux is using a resolution supported byUST-IP at a standard VESA resolution and refresh rate. Each Linux target server should also be set so theblanking times are within +/- 40% of VESA standard values.To check for these parameters:• Go to the Xfree86 Configuration file XF86Config• Using a text editor, disable all non-UST-IP supported resolutions• Disable the virtual desktop feature, which is not supported by UST-IP• Check blanking times (+/- 40% of VESA standard).• Restart computerNote: In many Linux graphical environments, the command will change the videoresolution, scrolling through all available resolutions that remain enabled in the XF86Config file.Sun Solaris SettingsAll target servers must be configured to one of the display resolutions supported by UST-IP. The mostpopular supported resolutions for Sun machines are:• 1024x768@60Hz• 1024x768@70Hz• 1024x768@75Hz• 1024x768@85Hz• 1152x900@66Hz• 1152x900@76Hz• 1280x1024@60HzTarget servers running the Solaris operating system must output VGA video (H-and-V sync, not compositesync). To change your Sun video card output from composite sync to the non-default VGA output, firstissue the Stop+A command to drop to bootprom mode. Then, issue the command:setenv output-device screen:r1024x768x70to change the output resolution. Issue the “boot” command to reboot the server.Alternatively, you may contact your Raritan representative to purchase a video output adapter. 13W3 Sunswith composite sync output require APSSUN II Raritan guardian for use with UST-IP. HD15 Suns withcomposite sync output require 1396C Raritan converter to convert from HD15 to 13W3 and an APSSUN IIRaritan guardian converter to support composite sync. HD15 Suns with separate sync output require anAPKMSUN Raritan guardian for use with UST-IP.Note that KVM switch brands other than Raritan’s may or may not properly handle PS/2-to-Sun signals.On target servers running the Solaris operating system, set the mouse acceleration value to exactly 1 andthreshold to exactly 1. Set this at the graphical user interface (shown below), or with the command line“xset mouse a t” where “a” is the acceleration and “t” is the threshold.
