Public bug reported: Laptop: Samsung NP550XDA-KS1BR Ubuntu 20.04
Laptop had windows 10 pre-installed. Then I installed ubuntu 18.04 and upgrade it to 20.04. The touchpad never worked in none. 2 things: In the BIOS the touchpad works normally. And it used to work at Windows OS. cat /proc/bus/input/devices > ~/devices I: Bus=0019 Vendor=0000 Product=0005 Version=0000 N: Name="Lid Switch" P: Phys=PNP0C0D/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/input/input0 U: Uniq= H: Handlers=event0 B: PROP=0 B: EV=21 B: SW=1 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=PNP0C0C/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0C:00/input/input1 U: Uniq= H: Handlers=kbd event1 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=LNXPWRBN/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 U: Uniq= H: Handlers=kbd event2 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0011 Vendor=0001 Product=0001 Version=ab83 N: Name="AT Translated Set 2 keyboard" P: Phys=isa0060/serio0/input0 S: Sysfs=/devices/platform/i8042/serio0/input/input4 U: Uniq= H: Handlers=sysrq kbd event3 leds B: PROP=0 B: EV=120013 B: KEY=500f02000403 3803078f870d001 feffffdffbefffff fffffffffffffffe B: MSC=10 B: LED=7 I: Bus=0003 Vendor=24ae Product=1100 Version=0110 N: Name="RAPOO Rapoo 2.4G Wireless Device" P: Phys=usb-0000:00:14.0-1/input0 S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-1/3-1:1.0/0003:24AE:1100.0001/input/input5 U: Uniq= H: Handlers=mouse0 event4 B: PROP=0 B: EV=17 B: KEY=1f0000 0 0 0 0 B: REL=903 B: MSC=10 I: Bus=0003 Vendor=13d3 Product=5a24 Version=2012 N: Name="VGA camera: VGA camera" P: Phys=usb-0000:00:14.0-7/button S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-7/3-7:1.0/input/input6 U: Uniq= H: Handlers=kbd event5 B: PROP=0 B: EV=3 B: KEY=100000 0 0 0 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HDA Intel PCH Headphone Mic" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:1f.3/sound/card0/input7 U: Uniq= H: Handlers=event6 B: PROP=0 B: EV=21 B: SW=4 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-81-generic 5.4.0-81.91 ProcVersionSignature: Ubuntu 5.4.0-81.91-generic 5.4.128 Uname: Linux 5.4.0-81-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.18 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: m 1439 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Mon Aug 30 10:54:58 2021 InstallationDate: Installed on 2021-08-25 (4 days ago) InstallationMedia: Ubuntu 18.04.3 LTS "Bionic Beaver" - Release amd64 (20190805) MachineType: SAMSUNG ELECTRONICS CO., LTD. 550XDA ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.4.0-81-generic root=UUID=aa140181-87e8-4760-b79a-6cc7eeffbc45 ro quiet splash i8042.nopnp=1 pci=nocrs vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.4.0-81-generic N/A linux-backports-modules-5.4.0-81-generic N/A linux-firmware 1.187.16 SourcePackage: linux UpgradeStatus: Upgraded to focal on 2021-08-26 (3 days ago) dmi.bios.date: 04/10/2021 dmi.bios.vendor: American Megatrends International, LLC. dmi.bios.version: P06CFB.032.210410.HQ dmi.board.asset.tag: No Asset Tag dmi.board.name: NP550XDA-KS1BR dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: SGLA915A03-C01-G001-S0001+10.0.19042 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInternational,LLC.:bvrP06CFB.032.210410.HQ:bd04/10/2021:svnSAMSUNGELECTRONICSCO.,LTD.:pn550XDA:pvrP06CFB:rvnSAMSUNGELECTRONICSCO.,LTD.:rnNP550XDA-KS1BR:rvrSGLA915A03-C01-G001-S0001+10.0.19042:cvnSAMSUNGELECTRONICSCO.,LTD.:ct10:cvrN/A: dmi.product.family: Notebook Plus2 dmi.product.name: 550XDA dmi.product.sku: SCAI-A5A5-A5A5-TGL3-PCFB dmi.product.version: P06CFB dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942088 Title: Touchpad not recognized in Samsung NP550XDA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1942088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
