- Lub Fedora Workstation desktop tau hloov kho rau GNOME 40 thiab GTK 4. Hauv GNOME 40, Cov Haujlwm Saib Xyuas Kev Ua Haujlwm virtual tau raug hloov mus rau qhov kev taw qhia toj roob hauv pes thiab tau tshwm sim hauv cov saw txuas txuas ntxiv ntawm sab laug mus rau sab xis. Txhua lub desktop tso tawm nyob rau hauv hom Txheej txheem cej luam pom qhov muaj qhov rais thiab dynamically pans thiab zooms raws li tus neeg siv cuam tshuam. Kev hloov pauv seamless yog muab nruab nrab ntawm cov npe ntawm cov kev pab cuam thiab virtual desktops. Txhim kho lub koom haum ntawm kev ua haujlwm thaum muaj ntau yam saib. Kev tsim qauv ntawm ntau cov kev pab cuam tau hloov kho tshiab. GNOME Plhaub txhawb kev siv GPU rau kev ua cov duab ntxoov ntxoo.
- Tag nrho cov ntawv ntawm Fedora tau raug hloov mus siv lub systemd-oomd mechanism rau cov lus teb thaum ntxov rau cov xwm txheej tsis nco ntawm lub kaw lus, es tsis txhob siv cov txheej txheem ntxov ntxov. Systemd-oomd yog ua raws li PSI (Pressure Stall Information) kernel subsystem, uas tso cai rau koj los tshuaj xyuas cov ntaub ntawv hais txog lub sijhawm tos kom tau txais ntau yam kev pabcuam (CPU, nco, I / O) hauv cov neeg siv qhov chaw kom raug ntsuas cov qib ntawm lub kaw lus. thiab qhov xwm txheej qeeb. PSI ua rau nws muaj peev xwm txheeb xyuas qhov pib ntawm kev ncua vim tsis muaj peev txheej thiab xaiv cov txheej txheem siv cov txheej txheem siv nyob rau theem thaum lub kaw lus tseem tsis tau nyob rau hauv lub xeev tseem ceeb thiab tsis pib siv zog txiav cov cache thiab thawb cov ntaub ntawv mus rau hauv kev sib pauv. muab faib.
- Cov ntaub ntawv Btrfs, uas txij li qhov kev tso tawm kawg tau ua lub neej ntawd rau desktop flavours ntawm Fedora (Fedora Workstation, Fedora KDE, thiab lwm yam), suav nrog cov ntaub ntawv pob tshab compression siv ZSTD algorithm. Compression yog lub neej ntawd rau kev teeb tsa tshiab ntawm Fedora 34. Cov neeg siv ntawm cov tshuab uas twb muaj lawm tuaj yeem ua kom compression los ntawm kev ntxiv "compress=zstd:1" chij rau /etc/fstab thiab khiav "sudo btrfs filesystem defrag -czstd -rv / /home/" mus compress cov ntaub ntawv uas twb muaj lawm. Txhawm rau ntsuas compression efficiency, koj tuaj yeem siv cov khoom siv "compsize". Nws raug sau tseg tias khaws cia cov ntaub ntawv hauv daim ntawv compressed tsis tsuas yog txuag qhov chaw disk, tab sis kuj ua rau lub neej kev pab cuam ntawm SSD tsav los ntawm kev txo qhov ntim ntawm kev sau ntawv, thiab tseem ua rau kom ceev ntawm kev nyeem ntawv thiab sau cov ntaub ntawv loj, zoo-compressed ntawm qeeb drives. .
- Cov ntawv tshaj tawm ntawm kev faib khoom suav nrog cov version nrog i3 qhov rais tus thawj tswj, uas muaj cov vuas qhov rais layout hom ntawm lub desktop.
