Problem
| Host OS | Win11 |
|---|---|
| Guest OS | Kubuntu 22.04 |
| vmware | vmware workstation pro 17.5 |
Every once in a while, my guest os went into a strange freezed state, where I could move the mouse, but the guest os just didn’t response.
I used to monitor those logs under /var/log, and system resource usage with top command, but nothing was found, until I saw the following line in vmware.log.
12024-03-06T16:33:01.365Z In(05) mks VMMouse: Dropping move received while input queue was full
This line was the last in the file, so it’s easy to find. Input was dropped, this explains everything.
Solve
I searched this error and found a post which was written many years ago in vmware community. Here is the solution:
Tip
- config.ini’s location may vary according to the os, please google it yourself
- config.ini may could not be saved due to permission issue, please save it to desktop and drag it to destination。
- vmx file is very important and you should backup it before making any changes to it。
- Add following two lines to C:\ProgramData\VMware\VMware Workstation\config.ini
1prefvmx.useRecommendedLockedMemSize = "TRUE" 2prefvmx.minVmMemPct = "100"
If you’re experiencing some keyboard issues, like typing ‘characterrrrrrrrr’, you might also need following two lines(not tested):
1mks.disableTypematic = "TRUE"
2mks.disableRemoteClientTypematic = "TRUE"
- Add following two lines to xxxx.vmx（located in the guest os root directory，please replace xxxx.vmx with the right name）
1sched.mem.pshare.enable = "FALSE" 2mainMem.useNamedFile = "FALSE" 3MemTrimRate = "0" 4MemAllowAutoScaleDown = "FALSE" - If the problem still exists, you might need to downgrade to 17.0.2 version of vmware workstation pro, and this line in vmx needs to be changed:
1virtualHW.version = "20"
I have no idea what those configurations are for but the problem never arises again. Amazing, right?
